description: We present a numerical study of the space-space and time-time components of the gluon propagator at equal time in the minimal Coulomb gauge, and of the gluon and ghost propagators in the minimal Landau gauge. This work allows a non-perturbative evaluation of the running coupling constant and a numerical check of Gribov's confinement scenarios for these two gauges. Our simulations are done in pure SU(2) lattice gauge theory at $β= 2.2$. We consider several lattice volumes in order to control finite-volume effects and extrapolate our results to infinite lattice volume.

description: With very high potential transit-depths and no stellar flare activity, the planets of White Dwarfs are some of the most promising in the search for detectable extraterrestrial life. We review the evidence that both terrestrial and gas-giant planets are capable of surviving post-main sequence evolution and migrating into the WD phase. We find that WDs are capable of hosting stable Habitable Zones outside orbital distances at which Earthmass planets would be disintegrated by tidal forces. To reach the WD phase, a main-sequence star has to progress along the Asymptotic Giant Branch (AGB) around which circumstellar envelopes are found to spectrally exhibit simple molecules from which amino acids and simple sugars can be synthesised. We find using a simple accretion model that even at distances on the scale of „ 100 AU, a mass of this material greater than that of the Earth’s atmosphere should be delivered to an Earth-mass planet.

description: We consider Lorentz-violating operators induced at the loop level in softly-broken supersymmetric noncommutative QED. Dangerous operators forbidden in the supersymmetric limit are generated via finite corrections, with the scale of supersymmetry breaking serving as a gauge-invariant regulator. We compare the most dangerous loop effects to those obtained in noncommutative theories truncated by a momentum-space cutoff, and find significantly improved bounds.

High-resolution spectroscopy

description: M dwarfs are attractive target stars for exoplanets. To assess exoplanet habitability around them, their atmospheric parameters need to be accurately determined. Advances in high-resolution spectroscopy in the near-infrared have opened up the possibility of improving M dwarf analysis. There have recently been several methods published on fitting the observed high-resolution spectra with synthetic spectra using different instruments and theoretical approaches. We present a comparison of stellar parameters derived by two different approaches for 11 different stars in common between three studies.
 The derived effective temperature values agree within uncertainties for most stars while the surface gravity and metallicity show a larger spread. For half of the stars, the differences are larger than the given uncertainties. To investigate the diverging results, we asses non-LTE effects in the parameter range of M dwarfs for K and Fe. Non-LTE effects are negligible for Fe I in M-dwarf atmospheres but are important for K I. These effects, leading to potassium abundance and metallicity corrections on the order of 0.2 dex, may be responsible for some of these discrepancies. The aim is to validate and improve the method of fitting synthetic spectra to observed spectra for M dwarfs.

description: This paper presents a comprehensive analysis of the Quantum Big Bounce model as an alternative to the classical Big Bang theory. It addresses the singularity problem by incorporating quantum corrections, avoiding the infinite density and curvature issues associated with the Big Bang. The study compares the theoretical foundations of both models and provides detailed numerical simulations exploring the impact of varying cosmological parameters, such as the quantum correction coefficient α\alphaα, initial curvature, and density fluctuations. Empirical predictions are made for future observations using instruments like JWST, LISA, and CMB-S4, which could validate or refute the Quantum Big Bounce model. Additionally, challenges and limitations of the model are discussed, with a focus on uncertainties in α\alphaα and its connection to Loop Quantum Gravity and String Theory.

description: Tunneling of two particles in synchronous and asynchronous regimes is studied in the framework of dissipative quantum tunneling. The critical temperature T_c corresponding to a bifurcation of the underbarrier trajectory is determined. The effect of a heat bath local mode on the probability of two-dimensional tunneling transfer is also investigated. At certain values of the parameters, the degeneracy of antiparallel tunneling trajectories is important. Thus, four, six, twelve, etc., pairs of the trajectories should be taken into account (a cascade of bifurcations). For the parallel particle tunneling the bifurcation resembles phase transition of a first kind, while for the antiparallel transfer it behaves as second order phase transition. The proposed theory allows for the explanation of experimental data on quantum fluctuations in two-proton tunneling in porphyrins near the critical temperature.

LRG-BEASTS: Ground-based Detection of Sodium and a Steep Optical Slope in the Atmosphere of the Highly Inflated Hot-Saturn WASP-21b
Creators: name: Alderson, Lili
Publisher: name: Zenodo
Year: 2021

description: We present the optical transmission spectrum of the highly inflated Saturn-mass exoplanet WASP-21b, using three transits obtained with the ACAM instrument on the William Herschel Telescope through the LRG-BEASTS survey (Low Resolution Ground-Based Exoplanet Atmosphere Survey using Transmission Spectroscopy). Our transmission spectrum covers a wavelength range of 4635-9000Å, achieving an average transit depth precision of 197ppm compared to one atmospheric scale height at 246ppm. Whilst we detect sodium absorption in a bin width of 30Å, at >4 sigma confidence, we see no evidence of absorption from potassium. Atmospheric retrieval analysis of the scattering slope indicates that it is too steep for Rayleigh scattering from H2, but is very similar to that of HD189733b. The features observed in our transmission spectrum cannot be caused by stellar activity alone, with photometric monitoring and Ca H&K analysis of WASP-21 showing it to be an inactive star. Our work demonstrates that WASP-21b is an excellent target for future infra-red observations.

description: The Galaxy And Mass Assembly (GAMA) survey has morphologically identified a class of "Little Blue Spheroid" (LBS) galaxies whose relationship to other classes of galaxies we now examine in detail. Considering a sample of 868 LBSs, we find that such galaxies display similar but not identical colours, specific star formation rates, stellar population ages, mass-to-light ratios, and metallicities to Sd-Irr galaxies. We also find that LBSs typically occupy environments of even lower density than those of Sd-Irr galaxies, where ~65% of LBS galaxies live in isolation. Using deep, high-resolution imaging from VST KiDS and the new Bayesian, two-dimensional galaxy profile modeling code PROFIT, we further examine the detailed structure of LBSs and find that their Sérsic indices, sizes, and axial ratios are compatible with those of low-mass elliptical galaxies. We then examine SAMI Galaxy survey integral field emission line kinematics for a subset of 62 LBSs and find that the majority (42) of these galaxies display ordered rotation with the remainder displaying disturbed/non-ordered dynamics. Finally, we consider potential evolutionary scenarios for a population with this unusual combination of properties, concluding that LBSs are likely formed by a mixture of merger and accretion processes still recently active in low-redshift dwarf populations. We also infer that if LBS-like galaxies were subjected to quenching in a rich environment, they would plausibly resemble cluster dwarf ellipticals.

Elucidating oncogenic mechanisms in human B cell malignancies

description: This study consists of two pieces of work investigating haematological malignancies; Acute Lymphoblastic Leukaemia (ALL) and Diffuse Large B Cell Lymphoma (DLBCL). Firstly, Pre-B ALL represents the most common paediatric malignancy and despite increasingly improved outcomes for patients, ~ 20% of all patients diagnosed with ALL relapse. Activating mutations in the RAS pathway are common (~50%) and result in hyperactivation of the MAPK pathway. I identified Erk negative feedback control via DUSP6 to be crucial for NRASG12D-mediated pre-B cell transformation and investigated its potential as a therapeutic target. I showed that a small molecule inhibitor of DUSP6 (BCI) selectively induced cell death in patient-derived pre-B ALL cells; with a higher sensitivity observed in relapse pre-B ALL. I also discovered that a high level of Erk activity is required for proliferation of normal pre-B cells, but dispensable in leukemic pre-B ALL cells. In addition, I found that human B cell malignancies can be grouped into three categories that fundamentally differ in their ability to control Erk signalling strength. Secondly, DLBCL is the most common haematological malignancy and although potentially curable with chemotherapy, 40% of patients still succumb from their disease. Recent exome sequencing studies have identified hundreds of genetic alterations but, for most, their contribution to disease, or their importance as therapeutic targets, remains uncertain. I optimised a novel approach to screen the functional importance of these mutations. This was achieved by reconstituting non-malignant, primary, human germinal centre B cells (GC B cells) with combinations of wildtype and mutant genes to recapitulate the genetic events of DLBCL. When injected into immunodeficient mice, these oncogene-transduced GC B cells gave rise to tumours that closely resemble human DLBCL, reinforcing the biological relevance of this system. To screen potential tumour suppressor mutations in this system in a high throughput fashion, I developed a lymphoma-focused CRISPR library of 692 genes recurrently altered in B cell lymphomas. These experiments identified GNA13 as an unexpectedly potent tumour suppressor in human GC B cells and provided new understanding to its mechanism of action. These findings provide novel understanding of the complexity of oncogenic mechanisms in human B cell malignancies.
The Role of the Parker Instability in Structuring the Interstellar Medium

description: The Parker instability, a Rayleigh-Taylor like instability of thermal gas supported against gravity by magnetic fields and cosmic rays, is thought to be dynamically important for galaxy evolution, possibly promoting molecular cloud formation and the galactic dynamo. In previous work, we examined the effect of three different cosmic ray transport models on the Parker instability: decoupled ($γ_c = 0$), locked to the thermal gas ($γ_c = 4/3$) and coupled to the gas with streaming by self-confinement. We expand upon that work here by considering radiative cooling, a smooth gravitational potential, and simulations into the nonlinear regime. We determine that cosmic ray transport away from compression points, whether by diffusion or streaming, is the largest driver of the instability. Heating due to cosmic ray streaming is also destabilizing and especially affects the nonlinear regime. While cooling de-pressurizes the dense gas, streaming cosmic rays heat and inflate the diffuse extraplanar gas, greatly modifying the phase structure of the medium. In 3D, we find that the fastest growth favors short wavelength modes in the horizontal direction perpendicular to the background magnetic field; this is imprinted on Faraday rotation measure maps that may be used to detect the Parker instability. The modifications to the Parker instability that we observe in this work have large implications for the structure and evolution of galaxies, and they highlight the major role that cosmic rays play in shaping their environments.

description: This work describes a laboratory plasma experiment and initial results which should give insight into the magnetic dynamics of accretion discs and jets. A high-speed multiple-frame CCD camera reveals images of the formation and helical instability of a collimated plasma, similar to MHD models of disc jets, and also plasma detachment associated with spheromak formation, which may have relevance to disc winds and flares. The plasmas are produced by a planar magnetized coaxial gun. The resulting magnetic topology is dependent on the details of magnetic helicity injection, namely the force-free state eigenvalue alpha_gun imposed by the coaxial gun.

description: Stellar activity poses one of the main obstacles for the detection and characterisation of exoplanets around cool stars, as it can induce radial velocity (RV) signals that can hide or mimic the presence of companions. Several activity indicators are routinely used to identify activity-related signals in RV measurements, but not all indicators trace exactly the same effects, nor are any of them always effective in all stars. In this work, we evaluate the performance of a set of common spectroscopic activity indicators for 98 M dwarfs observed with CARMENES. We find that different indicators behave differently depending on the mass and activity level of the target star. In addition, we also observe that stars at the low-mass end of the sample show the lowest RV scatter, which could potentially hint at different manifestations of activity compared to higher-mass stars, as well as being better candidates for planet searches. Overall, our results show that when assessing the origin of an RV signal, it is critical to take into account a large set of indicators, or at least the most effective ones considering the characteristics of the star, as failing to do so may lead to false planet claims.

description: In many shell model interactions, the tensor force monopole matrix elements often retain systematic trends originating in the bare tensor force. In this work, however, we note for GX-interactions of \textit{pf}-shell that the seven out of ten T = 1 tensor force monopole matrix elements do not share these systematic. We ameliorate this disparity making use of Yukawa-type tensor force and spin-tensor decomposition. Furthermore, we modify the single-particle energy of $1p_{3/2}$ orbit and two TBMEs of $0f$-orbit,and test the revised interaction from Ca to Ge isotopes with various physics viewpoints. The results are found to be satisfactory with respect to the experimental data.

description: Since 1973, inflation has been a pervasive phenomenon affecting the agricultural sectors of most developed and developing countries. Despite its current significance, the issue of inflation and its impact on the agricultural sector is remarkably under-researched. In this paper we assess some of the economic impacts of inflation on Canadian agriculture in an attempt to isolate major influences and their effects. We consider effects on the prices of farmland, the increased risk and uncertainty affecting the industry, and a possible deterioration in the terms of trade between agriculture and the rest of the economy. We assess the effect of these and other inflation related influences on efficiency, productivity, and equity in the Canadian agricultural sector. The general conclusion of the paper is that the impacts of inflation on efficiency and productivity appear to have been minor compared to its distributional effects.

description: In Gribov's scenario in Coulomb gauge, confinement of color charge is due to a long-range instantaneous color-Coulomb potential V(R). This may be determined numerically from the instantaneous part of the gluon propagator D_{44, inst} = V(R) δ(t). Confinement of gluons is reflected in the vanishing at k = 0 of the equal-time three-dimensionally transverse would-be physical gluon propagator D^{tr}(k). We present exact analytic results on D_{44} and D^{tr} (which have also been investigated numerically, A. Cucchieri, T. Mendes, and D. Zwanziger, this conference), in particular the vanishing of D^{tr}(k) at k = 0, and the determination of the running coupling constant from x_0 g^2(k) = k^2 D_{44, inst}, where x_0 = 12N/(11N-2N_f).

Productivity Analysis

description: Whereas the treatment of space in economic analysis leaves much to be desired, the economic policy issues raised by the existence of spatial disparities are prominent in many debates, as illustrated for instance at the international level by the debate around the need for a new international economic order and at the national level by the discussions about regional development policies. Some authors argue that the latter are not very important since spatial income disparities play a very useful role as incentives for the geographic mobility of resources required by economic growth. We intend to show that such a position, which corresponds to a clear preference for growth over equity considerations, is not tenable for policy analysis. Conversely, the call for attention to equity considerations alone leads to very distorted and partial policy recommendations, as illustrated for instance by much of the rhetoric on international development. In order to go beyond these ideological positions, one must assess more precisely the nature of the issues. The need for a theoretical detour regarding the treatment of space in economics will then appear before returning in the third part of this paper to the policy issues raised first.

description: This thesis presents the development of all-inkjet-printed low-voltage organic thin-film transistors. Organic thin-film transistors (OTFTs), taking advantage of low-temperature printability, mechanical flexibility, and multi-functionality, are promising for a wide range of emerging applications such as wearable electronics. Printed OTFTs provide great benefits in fabrication cost reduction, but they need a very high operating voltage and exhibit severe instability during storage and operation in ambient environment. In this study, all-inkjet-printed OTFTs with a low operating voltage of less than 3 V are demonstrated through reducing trap density in the fabricated devices. The transistors use 6,13-bis(triisopropylsilylethynyl)pentacene as the semiconductor, poly(4-vinylphenol) as the dielectric, silver as the electrodes, and CYTOP as the encapsulation. Several aspects of physical and chemical properties of polymer dielectrics are studied to achieve this goal, including cross-linking, wetting, and moisture affinity. Through the careful selection of device architecture and control of the inkjet-printing processes, the semiconductor-dielectric interface trap density of the fabricated OTFTs is significantly reduced. The applicability of this approach to different materials is also investigated and confirmed, including polyvinyl cinnamate as the dielectric, 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene as the semiconductor, and anisole as the solvent for semiconductor inks. Based on the investigation of different materials, the characteristics and parameters of all-inkjet-printed OTFTs are optimised, demonstrating an ultra-steep subthreshold of 60.2 mV/decade approaching the theoretical limit and a low operating voltage of 1 V. In order to explore their feasibility in real-world applications, the stability of all-inkjet-printed OTFTs is investigated and the factors of instability are analysed. Based on these findings, the stability of the fabricated device is improved, such that the threshold voltage shift is less than 0.1 V in ambient environment storage for 3 months and operation for 1 hour. The electrical characteristics of OTFTs in the subthreshold regime are studied for analogue circuit design. Based on the developed low-voltage stable transistors, an ultra-low-power (< 1 nW) high-gain (> 200 V/V) amplifier is presented and utilised to detect electrophysiological signals from the human body.

description: We have analysed the NA50 data, on the centrality dependence of $p_T$ broadening of $J/ψ$'s, in Pb+Pb collisions, at the CERN-SPS. The data were analysed in a QCD based model, where $J/ψ$'s are suppressed in 'nuclear' medium. Without any free parameter, the model could explain the NA50 $p_T$ broadening data. The data were also analysed in a QGP based threshold model, where $J/ψ$ suppression is 100% above a critical density. The QGP based model could not explain the NA50 $p_T$ broadening data. We have also predicted the centrality dependence of $J/ψ$ suppression and $p_T$ broadening at RHIC energy. Both the models, the QGP based threshold model and the QCD based nuclear absorption model, predict $p_T$ broadening very close to each other.

To achieve this, our previous 3D reconstruction from multiple 2D-echo at standard cross-sections is extended by 1) reconstructing valves (aortic and mitral valves) from 2D-echo images and the superior wall; 2) optimizing the location and orientation of the surfaces to incorporate the physiological assumption of fixed apex as a reference (fixed) point for reconstruction; and 3) incorporating several smoothing algorithms to remove the nonphysical oscillations (ringing) near the basal section observed in our previous study. The main parameters of the reconstructed left ventricle (LV) are all within the physiologic range. Our results show that the mitral valve can significantly change the flow pattern inside the LV during the diastole phase in terms of ring vortex formation/propagation as well as the flow circulation. In addition, the abnormal shape of unhealthy LV can drastically change the flow field during the diastole phase. Furthermore, the hemodynamic energy loss, as an indicator of the LV pumping performance, for different test cases is calculated which shows a larger energy loss for unhealthy LV compared to the healthy one.

description: This dissertation examines the application and effect of Article 1 of the First Protocol to the ECHR in relation to Scots land law reform. Chapter one will reflect on why existing rights to property have come to be challenged. Chapter two sets out the human rights paradigm and scrutinises what rights and whose rights are engaged. Chapter three traces the development of A1P1. Chapter four applies the human rights paradigm to contemporary reforms. Chapter five considers the broader effect A1P1 has had on domestic property law. This dissertation submits that the problem to be overcome is that, in many instances, Scots land law reform has been reduced into a simplistic struggle. A1P1 has been held up as either a citadel protecting landowners or as an ineffective and unjustified right to be ignored. At the core of this debate are competing claims between liberal individualist rights to property and socially democratic, egalitarian goals. This dissertation argues that it is important to move beyond this binary debate. This is not about finding some mysterious “red card” or eureka moment that conclusively shows compatibility or incompatibility. Instead, compatibility will be determined by following a rule-based approach that values rational decision-making and the best available evidence, as well as the importance of democratic institutions. As such, it will be illustrated how future challenges are likely to focus not on the underlying purpose of land law reform but on the macro or micro granularity of Ministerial discretion. In coming to this conclusion, it will be argued that A1P1 has a pervasive influence on the entire workings of all public bodies and, like a dye, permeates the legislative process.

description: The origins of recently reported anisotropy of the local velocity field of nearby galaxies (velocities < 500 km/s corresponding to the distance less than 8 Mpc) are studied. The exact solution of the Newtonian equation for the expanding Universe is obtained. This solution allows us to separate the Newtonian motion of nearby galaxies from the Hubble flow by the transition to the conformal coordinates. The relation between the Hubble flow and the Newtonian motion is established. We show that the anisotropic local velocity field of nearby galaxies can be formed by such a Newtonian motion in the expanding Universe, if at the moment of the capture of galaxies by the central gravitational field.

Behavior of Fermi Systems Approaching Fermion Condensation Quantum Phase Transition from Disordered Phase

description: The behavior of Fermi systems which approach the fermion condensation quantum phase transition (FCQPT) from the disordered phase is considered. We show that the quasiparticle effective mass $M^*$ diverges as $M^*\propto 1/|x-x_{FC}|$ where $x$ is the system density and $x_{FC}$ is the critical point at which FCQPT occurs. Such a behavior is of general form and takes place in both three dimensional (3D) systems and two dimensional (2D) ones. Since the effective mass $M^*$ is finite, the system exhibits the Landau Fermi liquid behavior. At $|x-x_{FC}|/x_{FC}\ll 1$, the behavior can be viewed as a highly correlated one, because the effective mass is large and strongly depends on the density. In case of electronic systems the Wiedemann-Franz law is held and Kadowaki-Woods ratio is preserved. Beyond the region $|x-x_{FC}|/x_{FC}\ll 1$, the effective mass is approximately constant and the system becomes conventional Landau Fermi liquid.

description: By comparing the current regulatory requirements with the hypothetical scenario of the enactment of an environmental quality standard (EQS) for hydrocarbon contamination in continental waters, the research assesses, using expert interviews, which scenario most benefits Mexico. The research also assesses the criteria to be considered when designing such EQS, and the institutional challenges to face when trying to enforce such EQS. Furthermore, the research briefly explores different public policy approaches to regulation of water quality, and future research topics.
description: The research assesses if Mexico will benefit from the enactment of an environmental quality standard (EQS) for water contaminated with hydrocarbons, in light of Mexico’s energy reform. In addition, the research assesses the institutional challenges faced when trying to enforce such EQS, and the design elements for any such standard. The research compares the current regulatory framework for water contaminated with hydrocarbons in Mexico, which requires the preparation of an environmental risk assessment (ERA) for each case, with the enactment of two hypothetical EQS. The comparison is conducted using a multi-criteria analysis and information is gathered via expert interviews. Results indicate that Mexico will benefit from the enactment of an EQS, however several institutional challenges need to be solved to ensure effective enforcement.

Stationary components of HeI in strong magnetic fields - a tool to identify magnetic DB white dwarfs

description: In only three of the 61 known magnetic white dwarfs helium has been identified unambiguously while about 20% of all non-magnetic stars of this class are known to contain HeI or HeII. Until recently, data for HeI data were available only for magnetic fields below 20MG. This changed with the publication of extensive data by the group in Heidelberg. The corresponding calculations have now been completed for the energetically lowest five states of singlet and triplet symmetry for the subspaces with |m| <= 3; selected calculations have been performed for even higher excitations. In strongly magnetized white dwarfs only line components are visible whose wavelengths vary slowly with respect to the magnetic field, particularly stationary components which have a wavelength minimum or maximum in the range of the magnetic fields strengths on the stellar surface. In view of the many ongoing surveys finding white dwarfs we want to provide the astronomical community with a tool to identify helium in white dwarfs for fields up to 5.3GG. To this end we present all calculated helium line components whose wavelengths in the UV, optical, and near IR vary slowly enough with respect to the field strength to produce visible absorption features. We also list all stationary line components in this spectral range. Finally, we find series of minima and maxima which occur as a result of series of extremal transitions to increasingly higher excitations. We estimated the limits for 8 series which can possibly give rise to additional absorption in white dwarf spectra; one strong absorption feature in GD229 which is yet unexplained by stationary components is very close to two estimated series limits.

Variable Stars in Leo A: RR Lyraes, Short-period Cepheids, and Implications on Stellar Content

description: We present the results of a search for short-period variable stars in Leo A. We have found 92 candidate variables, including eight candidate RR Lyrae stars. From the RR Lyraes, we measure a distance modulus of (m-M)_0 = 24.51 +/- 0.12, or 0.80 +/- 0.04 Mpc. This discovery of RR Lyraes confirms, for the first time, the presence of an ancient (> ~11 Gyr) population in Leo A accounting for at least 0.1% of the galaxy's V luminosity. We have also discovered a halo of old (> ~2 Gyr) stars surrounding Leo A, with a scale length roughly 50% larger than that of the dominant young population. We also report the discovery of a large population of Cepheids in Leo A. The median absolute magnitude of our Cepheid sample is M_V = -1.1, fainter than 96% of SMC and 99% of LMC Cepheids. Their periods are also unusual, with three Cepheids that are deduced to be pulsating in the fundamental mode having periods of under 1 day. Upon examination, these characteristics of the Leo A Cepheid population appear to be a natural extension of the classical Cepheid period-luminosity relations to low metallicity, rather than being indicative of a large population of ``anomalous'' Cepheids. We demonstrate that the periods and luminosities are consistent with the expected values of low-metallicity blue helium-burning stars (BHeBs), which populate the instability strip at lower luminosities than do higher-metallicity BHeBs.

Topology and pion correlators -- a study in the N_f=2 Schwinger model

description: I readdress the issue whether the topological charge of the gauge background has an influence on a hadronic observable. To this end pion correlators in the Schwinger model with 2 dynamical flavours are determined on subensembles with a fixed topological charge. It turns out that the answer depends on a specific function of the sea-quark mass and the box volume which is in close analogy to the Leutwyler-Smilga parameter in full QCD.

Subjects: Circumstellar Disks

description: Debris disk morphology provides information about the dynamical environment of circumstellar dust. Asymmetry and other shape distortions can signal that the disk is interacting with the ISM or being stirred by nearby planets. For this study, we analyzed GPI corona graphic images of the disk around HD 15115, dubbed the “blue needle.” Previous studies with STIS, SPHERE, and ALMA have shown a brightness asymmetry and suggested that two distinct dust belts might orbit the star. Our analysis reveals the same brightness asymmetry, plus a warp on the Eastern limb. A future research goal is to search for evidence of a second dust belt.
