description: The study of the X-ray emission from massive binaries constitutes a relevant approach to investigate shock physics. The case of short period binaries may turn out to be quite challenging, especially in very asymmetric systems where the primary wind may overwhelm that of the secondary in the wind interaction. Our objective consists in providing an observational diagnostic of the X-ray behaviour of HD93205, that is a very good candidate to investigate these aspects. We analysed 31 epochs of XMM-Newton X-ray data spanning about two decades to investigate its spectral and timing behaviour. The X-ray spectrum is very soft along the full orbit, with a luminosity exclusively from the wind interaction region in the range of 2.3 -- 5.4\,$\times$10$^{32}$\,erg\,s$^{-1}$. The light curve peaks close to periastron, with a rather wide pre-periastron low-state coincident with the secondary's body hiding a part of the X-ray emitting region close to its surface. We determined a variability time scale of 6.0807\,$\pm$\,0.0013\,d, in full agreement with the orbital period. Making use of a one-dimensional approach to deal with mutual radiative effects, our results point to a very likely hybrid wind interaction, with a wind-photosphere occurring along most of the orbit, while a brief episode of wind-wind interaction may still develop close to apastron. Beside mutual radiative effects, the radiative nature of the shock that leads to some additional pre-shock obliquitity of the primary wind flow certainly explains the very soft emission. HD93205 constitutes a relevant target to investigate shock physics in short period, asymmetric massive binary systems, where various mutual radiative effects and radiative shocks concur to display an instructive soft X-ray behaviour. HD93205 should be considered as a valid, though challenging target for future three-dimensional modelling initiatives.

Remarks. It was not possible to borrow the holotype of A. buckmani from NMNZ. As the species is monotypic and, therefore, the original description is based only on one adult individual, Bitner´s descriptions of specimens of A. buckmani collected from Fiji provide further information about this species. This together with the published reinvestigation of the holotype (MacKinnon et al. 2008) provided sufficient information to (a) support the hypothesis of A. buckmani as a separate species, and (b) to distinguish it from the new species of Amphithyris described below. For detailed re-descriptions see Bitner (2006, 2008) and MacKinnon et al. (2008).

description: Context. The formation of stars has been subject to extensive studies in the past decades from molecular cloud to protoplanetary disk scales. It is still not fully understood how the surrounding material in a protostellar system, that often shows asymmetric structures with complex kinematic properties, feeds the central protostar(s) and their disk(s). Aims. We study the spatial morphology and kinematic properties of the molecular gas surrounding the IRS3A and IRS3B protostellar systems in the L1448N region located in the Perseus molecular cloud. Methods. We present 1 mm NOEMA observations of the PRODIGE large program and analyze the kinematic properties of molecular lines. Given the complexity of the spectral profiles, the lines are fitted with up to three Gaussian velocity components. The clustering algorithm DBSCAN is used to disentangle the velocity components into the underlying physical structure. Results. We discover an extended gas bridge (~3000 au) surrounding both the IRS3A and IRS3B systems in six molecular line tracers (C18O, SO, DCN, H2CO, HC3N, and CH3OH). This gas bridge is oriented along the northeast-southwest direction and shows clear velocity gradients on the order of 100 km/s/pc towards the IRS3A system. We find that the observed velocity profile is consistent with analytical streamline models of gravitational infall towards IRS3A. The high-velocity C18O (2-1) emission towards IRS3A indicates a protostellar mass of ~1.2 Msun. Conclusions. While high angular resolution continuum data often show IRS3A and IRS3B in isolation, molecular gas observations reveal that these systems are still embedded within a large-scale mass reservoir with a complex spatial morphology as well as velocity profiles. The kinematic properties of the extended gas bridge are consistent with gravitational infall toward the IRS3A protostar.

description: The molecular triangular lattice system, beta'-EtMe3Sb[Pd(dmit)2]2, is considered as a candidate material for the quantum spin liquid (QSL) state, although ongoing debates arise from recent controversial results. Here, the results of electron spin resonance (ESR) and muon spin relaxation (muSR) measurements on beta'-EtMe3Sb[Pd(dmit)2]2 are presented. Both results indicate characteristic behaviors related to quasi-one-dimensional (q1D) spin dynamics, whereas the direction of anisotropy found in ESR is in contradiction with previous theories. We succeed in interpreting the experiments by combining density-functional theory calculations and analysis of the effective model taking into account the multi-orbital nature of the system. While the QSL-like origin of beta'-EtMe3Sb[Pd(dmit)2]2 was initially attributed to the magnetic frustration of the triangular lattice, it appears that the primary origin is a 1D spin liquid resulting from the dimensional reduction effect.

description: Statistical studies show that stars of GK spectral types, with masses below 1.1 Sun mass, are depleted in hot Jupiters. This finding is evidence of tidal orbital decay during the main-sequence lifetime. Theoretical considerations show that in some configurations, the tidal energy dissipation can be boosted by non-linear effects in dynamical tides, which are wave-like responses to tidal forcing. To probe the regime of these dynamical tides in GK stars, we searched for orbital period shortening for 6 selected hot Jupiters in systems with 0.8-1 Sun mass host stars: HATS-18, HIP 65A, TrES-3, WASP-19, WASP-43, and WASP-173A. For the hot Jupiters of our sample, we analysed transit timing data sets based on mid-transit points homogeneously determined from observations performed with the Transiting Exoplanet Survey Satellite and high-quality data available in the literature. For the TrES-3 system, we also used new transit light curves we acquired with ground-based telescopes. The mid-transit times were searched for shortening of orbital periods through statistical testing of quadratic transit ephemerides. Theoretical predictions on the dissipation rate for dynamical tides were calculated under the regimes of internal gravity waves (IGWs) undergoing wave breaking (WB) in stellar centres and weak non-linear (WNL) wave-wave interactions in radiative layers. Stellar parameters of the host stars, such as mass and age, which were used in those computations, were homogeneously redetermined using evolutionary models with the Bayesian inference. We found that transit times follow the refined linear ephemerides for all ultra-hot Jupiters of our sample. Non-detection of orbital decay allowed us to place lower constraints on the tidal dissipation rates in those planet-star systems. In three systems, HATS-18, WASP-19, and WASP-43, we reject a scenario with total dissipation of IGWs. We conclude that...

Type material. Holotype: NMNZ Br 1455, Paratypes: NMNZ Br 1069
Type locality. Cook Strait, near Wellington, New Zealand.
Material examined. Paratypes (10): NMNZ Br 1069
Additional material. NZGS BR 2288
Diagnosis. Dorsibiconvex shell, weak capillae on dorsal valve exterior and ventral valve exterior. Dorsal median septum absent.
Description. Very small species of Amphithyris. Shell dorsibiconvex, roundly subquadrate, transparent. Dorsal valve more inflated than ventral valve and without median septum (Fig. 4 A). Large amphithyrid foramen (Fig. 4 B), short socket ridges reach beyond posterior shell edge (Fig. 4 C). Exterior surface smooth with weak capillae (Fig.
4C). More inflated than ventral valve (Fig. 4 C and F). Ventral valve with small emergent hinge teeth not parallel to long straight hinge line (Fig. 4 D). Very weak muscle impressions visible (Fig. 4 E). Exterior surface smooth with weak capillae (Fig. 4 F).
Remarks. A. parva was described by MacKinnon et al. (2008) on the basis of apparent 'topotypic' material of A. buckmani. Both Foster (1974) and Campbell & Fleming (1981) were unable to locate Thomson's holotype of A. buckmani (NMNZ Br 80) for comparison with their new species (A. hallettensis Foster, 1974 and A. richardsonae Campbell & Fleming, 1981) and instead used what were assumed to be immature specimens collected later (NMNZ Br 1069) and "five additional juveniles attached to a concretionary boulder from the Outer Island Bay Bank (NZGS BR 2288)" (Campbell & Fleming 1981: p. 147–148). After their re-discovery of the holotype of A. buckmani at NMNZ, MacKinnon and co-workers came to the conclusion that the immature specimens assigned to A. buckmani by Foster (1974) and Campbell & Fleming (1981) belong to a new species, A. parva, which according to our study differs from the other species by its dorsibiconvex shells, the absence of a dorsal median septum and the presence of capillae on the outside of both dorsal and ventral valve. The material from Outer Island Bay Bank (NZGS BR 2288) was assigned to A. parva (MacKinnon et al. 2008), but not listed as type material.

TYPE MATERIAL EXAMINED: 1 ♀ paratype; Indonesia, West Sumatra, Panti Reserve, north of Lebuksikaping (= Lubuksikaping), leaf litter in lowland primary forest; 4.VIII.1982; C.L. & P.R. Deeleman leg. (RMNH).
NEW MATERIAL: 1 ♀; Indonesia, Sumatra, West Sumatra Province, old secondary forest above Harau Canyon, north of Payakumbuh, 750 m; 7.VI.2006; leg. P.J. Schwendinger (MHNG, sample Sum-06/11).
REMARKS: Deeleman-Reinhold (2001: 419) provided a description and illustrations of the female paratype. The female of this species is recognized by the absence of anterior membranous bursae, by the thick-walled copulatory ducts, and by the specific shape of the spermathecae (Fig. 33). We present here another unique character found only in the female of this species: a digitiform appendage situated on the anterior surface of each spermatheca (Figs 28, 33-34).

Evidence for a Sharp CO Snowline Transition in a Protoplanetary Disk and Implications for Millimeter-wave Observations of CO Isotopologues

description: Observations of CO isotopologue emission from protoplanetary disks at millimeter wavelengths are a powerful tool for probing the CO snowline, an important marker for disk chemistry, and also for estimating total disk gas mass, a key quantity for planet formation. We use simple models to demonstrate that the vertical thickness of an isothermal layer around the disk midplane has important effects on the CO column density radial profile, with a thick layer producing a sharp CO snowline transition. We simulate ngVLA and ALMA images to show that this sharp change in CO column density can be detected in the derivative of the radial profile of emission from optically thin CO isotopologue lines. We apply this method to archival ALMA observations of the disk around the Herbig Ae star HD 163296 in the C$^{17}$O and C$^{18}$O J=1-0 and J=2-1 lines to identify a sharp CO snowline transition near 80 au (0.8 arcsec at 101 pc), and show the CO column density decreases by more than a factor of 20. This finding is consistent with previous inferences from the steep rise of N$_2$H$^+$ emission, which marks the location where CO depletes. We also demonstrate that the disk's thermal structure introduces a significant systematic uncertainty to estimates of total disk gas mass derived from these lines. The substantial improvement in sensitivity envisioned for the ngVLA over ALMA for observations of ground-state lines of CO isotopologues has the potential to extend this approach to a much larger population of disks.

description: Evidence for similar chemical characteristics around low- and high-mass protostars has been found: in particular, a variety of carbon-chain species and complex organic molecules (COMs) are formed around them. On the other hand, the chemical compositions around intermediate-mass (IM; $2 M_{\odot} < m_* <8 M_{\odot}$) protostars have not been studied with large samples. In particular, it is unclear the extent to which carbon-chain species are formed around them. We aim to obtain the chemical compositions, particularly focusing on carbon-chain species, towards a sample of IM protostars. We have conducted Q-band (31.5-50 GHz) line survey observations towards eleven mainly intermediate-mass protostars with the Yebes 40 m radio telescope. The target protostars were selected from a sub-sample of the source list of the SOFIA Massive (SOMA) Star Formation project. Nine carbon-chain species (HC$_3$N, HC$_5$N, C$_3$H, C$_4$H, $linear-$H$_2$CCC, $cyclic-$C$_3$H$_2$, CCS, C$_3$S, and CH$_3$CCH), three COMs (CH$_3$OH, CH$_3$CHO, and CH$_3$CN), H$_2$CCO, HNCO, and four simple sulfur (S)-bearing species ($^{13}$CS, C$^{34}$S, HCS$^+$, H$_2$CS) have been detected. The rotational temperatures of HC$_5$N are derived to be $\sim20-30$ K in three IM protostars and they are very similar compared to those around low- and high-mass protostars. These results indicate that carbon-chain molecules are formed in lukewarm ($\sim20-30$ K) gas around the IM protostars by the Warm Carbon-Chain Chemistry (WCCC) process. Carbon-chain formation occurs ubiquitously in the warm gas around protostars across a wide range of stellar masses. Carbon-chain molecules and COMs coexist around most of the target IM protostars, which is similar to the situation in low- and high-mass protostars. The chemical characteristics around protostars are common in the low-, intermediate- and high-mass regimes.

description: The Newtonian restricted three-body problem involving a positive primary point mass, $m_+$, and a negative secondary point mass, $m_-$, in a circular orbit, and a positive or negative tertiary point mass, $m_3$, with $m_+ > |m_-| \gg |m_3|$, is solved. Five Lagrange points are found for $m_3$, three of which are coplanar with $m_+$ and $m_-$, and two of which are not, a subtle consequence of the gravitational repulsion from $m_-$. All Lagrange points are linearly unstable, except for one point in the regime $m_+ \gtrsim 8.4 |m_-|$, which is linearly stable and collinear with $m_+$ and $m_-$.
Role of octupole shape degree of freedom in neutron-rich odd-mass xenon isotopes

description: Influences of the octupole shape degree of freedom on low-energy spectra of neutron-rich odd-mass xenon isotopes are studied within the interacting boson-fermion model that is based on the nuclear density functional theory. The interacting-boson Hamiltonian describing low-energy quadrupole and octupole collective states of the even-even nuclei $^{140,142,144}$Xe, single-particle energies, and occupation probabilities for an unpaired neutron in the odd-mass nuclei $^{141,143,145}$Xe, are determined based on the axially symmetric quadrupole-octupole deformation-constrained self-consistent mean-field calculations with a choice of the energy density functional and pairing interaction. Strength parameters of the boson-fermion interactions are empirically determined to reproduce a few low-lying levels of each odd-mass nucleus. The mean-field calculation predicts for $^{142}$Xe a potential energy surface that is notably soft in the octupole deformation with a non-zero octupole global minimum. The octupole correlations are shown to be relevant in positive-parity excited states of $^{143,145}$Xe.

description: Using the folding procedure, we investigate the bound state of the $Ω$+$α$ system based on $Ω$-$N$ ($^{5}S_{2}$) HAL QCD potential. Previous theoretical analyses have indicated the existence of a deeply bound ground state, which is attributed to the strong $Ω$-nucleon interaction. By employing well-established parameterizations of nucleon density within the alpha particle, and the central HAL QCD $Ω$-$N$ potential, we performed numerical calculations for the folding $Ω$-$α$ potential. Our results show that the $V_{Ωα}(r)$ potential can be accurately fitted using a Woods-Saxon function, with a phenomenological parameter $R = 1.1A^{1/3} \approx 1.74$ fm ($A=4$) in the asymptotic region where $2 < r < 3$ fm. We provide a thorough description of the corresponding numerical procedure. Our evaluation of the binding energy of the $Ω$+$α$ system within the cluster model is consistent with both previous and recent reported findings. To further validate the folding procedure, we also calculated the $Ξ$-$α$ folding potential based on a simulation of the ESC08c $Y$-$N$ Nijmegen model. A comprehensive comparison between the $Ξ$-$α$ folding and $Ξ$-$ α$ phenomenological potentials is presented and discussed.

REMARKS: Otacilia kao is a pale species with extremely elongated and slender legs. There is a modest variation between the male holotype and the newly collected spiders examined and treated in the present study. The apex of the retrolateral tibial apophysis is slightly different from that of the male holotype (Figs 35, 37). The new male’s palpal configuration closely resembles that of O. sinifera and O. kao in having a simple, curved embolus and a minute conductor (Figs 35-36), but O. sinifera can be distinguished by the apex of the retrolateral tibial apophysis being hook-shaped, in addition to its conspicuous opisthosomal pattern. The shape of the retrolateral tibial apophysis in all three species seems to be somewhat similar, so it is difficult to make a conclusion about the taxonomic value of this character. They can be considered as a rather compact group of closely related species. It is possible that O. kao is a species with strong variability within the species and within its populations. However, the variation found in the new males is well within the known limits of the species and is not sufficient to warrant the status of a new taxon.

description: The time lag between soft and hard X-ray photons has been observed in many active galactic nuclei (AGN) and can reveal the accretion process and geometry around supermassive black holes (SMBHs). High-frequency Fe K and soft lags are considered to originate from the light-travel distances between the corona and the accretion disk, while the propagation of the inward mass accretion fluctuation usually explains the low-frequency hard lags. Ultra-fast outflows (UFOs), with a velocity range of 0.03-0.3c, have also been discovered in numerous AGN and are believed to be launched from the inner accretion disk. However, it remains unclear whether UFOs can affect the X-ray time lags. As a pilot work, we aim to investigate the potential influence of UFOs on X-ray time lags of AGN in a small sample. By performing the UFO-resolved Fourier spectral timing analysis of archival XMM-Newton observations of three AGN with transient UFOs: PG 1448+273, IRAS 13224-3809, and PG 1211+143, we compare their X-ray timing products, such as lag-frequency and lag-energy spectra, of observations with and without UFO obscuration. Our results find that in each AGN, low-frequency hard lags become weak or even disappear when they are accompanied by UFOs. In the high-frequency domain, soft lags remain unchanged while the Fe K reverberation lags tentatively disappear. The comparison between timing products of low- and high-flux observations on another three AGN without UFOs (Ark 564, NGC 7469, and Mrk 335) suggests that the disappearance of low-frequency hard lags is likely related to the emergence of UFOs, not necessarily related to the source flux. We conclude that the presence of UFOs can affect X-ray time lags of AGN by suppressing the low-frequency hard lags, which can be explained by an additional time delay introduced by UFOs or disk accretion energy carried away by UFOs.

This single female is closely related to T. terricoloides Shamshev & Grootaert, 2005, but because the male is unknown, we did not name it. The antennae are completely yellow and the basal segments are not darkened as in T. terricoloides. It has a black thorax instead of the yellowish-brown thorax in T. terricoloides. There is a pair of pale dorsocentrals near the middle of the mesonotum that are longer than the other dorsocentrals. The halter has a black knob rather than a yellow knob. The legs are completely yellow including all coxae, but tip of fore tarsomere 1 is ventrally brown, fore tarsomeres 2 and 3 are clear yellow, tip of tarsomere 4 and apical half of tarsomere 5 brown. Tips of mid and hind tarsomeres 4 and 5 brown.
