Spectroscopic Orbits of Subsystems in Multiple Stars. VIII.
Authors: Tokovinin Andrei
Published: March 2022

Periods, eccentricities, and masses in hierarchical stellar systems inform us on the formation and early evolution of these fascinating objects. To complement the multiplicity statistics of nearby solar-type stars, 19 new spectroscopic orbits of inner subsystems in 15 hierarchies (10 triples and 5 quadruples) are determined based on high-resolution echelle spectra collected during several years. While previous papers of this series contained mostly short-period orbits, here most periods are on the order of a year. The main components of these hierarchies are HIP 7852, HIP 9148, HIP 12548, HIP 21079, HIP 24320, HIP 27970, HIP 34212, HIP 56282, HIP 57860, HIP 76400, HIP 76816, HIP 81394, HIP 96284, HIP 100420, and HD 108938. Noteworthy systems are HIP 12548 and HIP 24230 (hierarchies of 2+2 architecture with low-mass spectroscopic secondaries), HIP 56282 (a planetary-type 3+1 hierarchy), and HIP 27970 (a compact triple with periods of 15 and 1049 days).

Kilonovae are ultraviolet, optical, and infrared transients powered by the radioactive decay of heavy elements following a neutron star merger. Joint observations of kilonovae and gravitational waves can offer key constraints on the source of Galactic r-process enrichment, among other astrophysical topics. However, robust constraints on heavy element production require rapid kilonova detection (within ∼1 day of merger) as well as multiwavelength observations across multiple epochs. In this study, we quantify the ability of 13 wide-field-of-view instruments to detect kilonovae, leveraging a large grid of over 900 radiative transfer simulations with 54 viewing angles per simulation. We consider both current and upcoming instruments, collectively spanning the full kilonova spectrum. The Roman Space Telescope has the highest redshift reach of any instrument in the study, observing kilonovae out to z ∼ 1 within the first day post-merger. We demonstrate that BlackGEM, DECam, GOTO, the Vera C. Rubin Observatory’s LSST, ULTRASAT, VISTA, and WINTER can observe some kilonovae out to z ∼ 0.1 (∼475 Mpc), while DDOTI, MeerLICHT, PRIME, Swift/UVOT, and ZTF are confined to more nearby observations. Furthermore, we provide a framework to infer kilonova ejecta properties following nondetections and explore variation in detectability with these ejecta parameters.

Ram pressure stripping (RPS) by the intracluster medium is one of the most advocated mechanisms that affect the properties of cluster galaxies. A recent study based on a small sample has found that many galaxies showing strong signatures of RPS also possess an active galactic nucleus (AGN), suggesting a possible correlation between the two phenomena. This result has not been confirmed by a subsequent study. Building upon previous findings, here we combine MUSE observations conducted within the GASP program and a general survey of the literature to robustly measure the AGN fraction in ram-pressure-stripped cluster galaxies using Baldwin–Phillips–Terlevich emission line diagrams. Considering a sample of 115 ram-pressure-stripped galaxies with stellar masses ≥ 109
M
⊙, we find an AGN fraction of ∼27%. This fraction strongly depends on stellar mass: it raises to 51% when only ram-pressure-stripped galaxies of masses M
* ≥ 1010
M
⊙ are considered. We then investigate whether the AGN incidence is in excess in ram-pressure-stripped galaxies compared to nonstripped galaxies using as a comparison a sample of noncluster galaxies observed by the MaNGA survey. Considering mass-matched samples, we find that the incidence of AGN activity is significantly higher (at a confidence level >99.95%) when RPS is in the act, supporting the hypothesis of an AGN–ram pressure connection.
A Note on the Construction of Explicit Symplectic Integrators for Schwarzschild Spacetimes
Authors: Zhou Naying , Zhang Hongxing , Liu Wenfang , Wu Xin
Published: March 2022

In recent publications, the construction of explicit symplectic integrators for Schwarzschild- and Kerr-type spacetimes is based on splitting and composition methods for numerical integrations of Hamiltonians or time-transformed Hamiltonians associated with these spacetimes. Such splittings are not unique but have various options. A Hamiltonian describing the motion of charged particles around the Schwarzschild black hole with an external magnetic field can be separated into three, four, and five explicitly integrable parts. It is shown through numerical tests of regular and chaotic orbits that the three-part splitting method is the best of the three Hamiltonian splitting methods in accuracy. In the three-part splitting, optimized fourth-order partitioned Runge–Kutta and Runge–Kutta–Nyström explicit symplectic integrators exhibit the best accuracies. In fact, they are several orders of magnitude better than the fourth-order Yoshida algorithms for appropriate time steps. The first two algorithms have a small additional computational cost compared with the latter ones. Optimized sixth-order partitioned Runge–Kutta and Runge–Kutta–Nyström explicit symplectic integrators have no dramatic advantages over the optimized fourth-order ones in accuracy during long-term integrations due to roundoff errors. The idea of finding the integrators with the best performance is also suitable for Hamiltonians or time-transformed Hamiltonians of other curved spacetimes including Kerr-type spacetimes. When the numbers of explicitly integrable splitting sub-Hamiltonians are as small as possible, such splitting Hamiltonian methods would bring better accuracies. In this case, the optimized fourth-order partitioned Runge–Kutta and Runge–Kutta–Nyström methods are worth recommending.
Stellar Revival and Repeated Flares in Deeply Plunging Tidal Disruption Events
Authors: Nixon C. J. , Coughlin Eric R.
Published: March 2022

Tidal disruption events with tidal radius r
t and pericenter distance r
p are characterized by the quantity β = r
t/r
p, and “deep encounters” have β ≫ 1. It has been assumed that there is a critical β ≡ β
c ∼ 1 that differentiates between partial and full disruption: for β < β
c a fraction of the star survives the tidal interaction with the black hole, while for β > β
c the star is completely destroyed, and hence all deep encounters should be full. Here we show that this assumption is incorrect by providing an example of a β = 16 encounter between a γ = 5/3, solar-like polytrope and a 106
M
⊙ black hole—for which previous investigations have found β
c ≃ 0.9—that results in the reformation of a stellar core post-disruption that comprises approximately 25% of the original stellar mass. We propose that the core reforms under self-gravity, which remains important because of the compression of the gas both near pericenter, where the compression occurs out of the orbital plane, and substantially after pericenter, where compression is within the plane. We find that the core forms on a bound orbit about the black hole, and we discuss the corresponding implications of our findings in the context of recently observed, repeating nuclear transients.
Circumbinary Disk Evolution in the Presence of an Outer Companion Star
Authors: Martin Rebecca G. , Lepp Stephen , Lubow Stephen H. , Kenworthy Matthew A. , Kennedy Grant M. , Vallet David
Published: March 2022

We consider a hierarchical triple system consisting of an inner eccentric binary with an outer companion. A highly misaligned circumbinary disk around the inner binary is subject to two competing effects: (i) nodal precession about the inner binary eccentricity vector that leads to an increase in misalignment (polar alignment) and (ii) Kozai–Lidov (KL) oscillations of eccentricity and inclination driven by the outer companion that leads to a reduction in the misalignment. The outcome depends upon the ratio of the timescales of these effects. If the inner binary torque dominates, then the disk aligns to a polar orientation. If the outer companion torque dominates, then the disk undergoes KL oscillations. In that case, the highly eccentric and misaligned disk is disrupted and accreted by the inner binary, while some mass is transferred to the outer companion. However, when the torques are similar, the outer parts of the circumbinary disk can undergo large eccentricity oscillations while the inclination remains close to polar orientation. The range of initial disk inclinations that evolve to a polar orientation is smaller in the presence of the outer companion. Disk breaking is also more likely, at least temporarily, during the polar alignment process. The stellar orbits in HD 98800 have parameters such that polar alignment of the circumbinary disk is expected. In the absence of gas, solid particles are unstable at much smaller radii than the gas-disk inner tidal truncation radius because KL-driven eccentricity leads to close encounters with the binary.
Quasi-periodic Dimming of the ∼130 Myr-old Debris-Disk Hosting Star HD 240779 is not Persistent
Authors: Gaidos Eric
Published: March 2022

Quasi-periodic (1.5 days) dimming (by circumstellar dust) of the 135 Myr-old AB Doradus moving group member HD 240779 was detected in photometry by TESS in late 2018. Similar observations two years later show no such signal, and ground-based photometry indicate that the signal was absent in late 2019. This suggests that the source of the dust did not survive long after 2018, e.g., it was a disrupted planetesimal, or that dust production by the body is episodic, analogous to the “evaporating” planets detected by Kepler.

Authors: Bistara Difran Nobel , Susanti Susanti , Setianto Budhi , Wardani Erika Martining , Krisnawati Dyah Ika , Satiti Nantiya Pupuh
Published: March 2022

BACKGROUND: In Indonesia, the four pillars of diabetes management include health education, food planning, physical exercise, and drug adherence. However, the most common imprudence in those four pillars was ignoring physical activity. Cycling has become a new social activity and a lifestyle among the community during the COVID-19 pandemic. It is an aerobic exercise that increases insulin receptor sensitivity.

AIM: This study aims to analyze the effect of cycling on Random Blood Glucose (RBG) levels in individuals with diabetes.

METHODOLOGY: This paper used a quasi-experiment pre-post test design with the control group. It utilized total sampling with 60 respondents. The independent variable was cycling using a dynamic bicycle. Meanwhile, the dependent variable was RBG levels with a glucometer as the instrument. The procedure in the intervention group was cycling using a dynamic bicycle twice a week with a distance of 2–3 kilometers each session. The data analysis used a paired T-test and independent sample T-test.

RESULTS: After cycling, the independent T-test result was p = 0.00 (p < 0.05). Thus, there was a difference in the mean RBG levels between the intervention and control groups after cycling. There was a decrease in mean RBG levels in the intervention group (206.67 ± 69.887 in pre-test and 114.60 ± 30.395 in post-test). In addition, the paired T-test resulted in p = 0.00 (p < 0.05). Thus, there was a difference in the intervention group’s mean RBG levels before and after cycling

CONCLUSION: Cycling can lower RBG levels in individuals with diabetes.

Authors: Christiyawati Maria , Estuningsih Estuningsih
Published: March 2022

BACKGROUND: Intellectual Quotients (IQ) is the ability to act purposefully, think rationally, and deal effectively with the environment. Emotional Quotients (EQ) includes empathy, expressing and understanding, feeling, controlling anger, independence, adaptability, liking, interpersonal problem-solving ability, perseverance, solidarity, friendliness, and respect; important for a person's success. Acupuncture therapy with Zhu Scalp and body acupuncture methods can be used to increase IQ and EQ in children.
AIM: This study was to determine the effectiveness of acupuncture therapy with Zhu Scalp acupuncture and body acupuncture methods on the IQ and EQ of pre-school children.
METHODS: The research method is a quantitative pre and post-test design with cross-sectional control with a paired T-test. The research sample was pre-school children in Sukoharjo district with a total of 54 respondents. The data collection instrument is a questionnaire for respondent characteristics, IQ test, and EQ measurement using VSMS (Vineland Social Maturity Scale).
RESULTS: The research results showed chitosan 5%; a combination of chitosan 9% and snail seromucous 50% (ratio 1: 1) is a microbicide against MTB TB patient isolates. Snail seromucous was ineffective as a microbicide against MTB tuberculosis patients.
The results showed that there was a significant difference in the IQ and EQ levels of children before and after acupuncture therapy using the Zhu Scalp method and body acupuncture with a p-value of 0.000. The results of the N Gain test showed that there are differences in the effectiveness of the Zhu Scalp acupuncture and the body acupuncture method on increasing IQ and EQ in pre-school children.
CONCLUSION: The Zhu Scalp acupuncture method is more effective than the body acupuncture method to increase IQ and EQ of pre-school age children, which can be applied in the management of acupuncture therapy to improve child development.

Lithium niobate is a ferroelectric material finding a wide range of applications in optical and acoustic engineering. Annealing of lithium niobate crystals in an oxygen-free environment leads to appearance of black coloration and concomitant increasing electrical conductivity due to chemical reduction. There are plenty of literary data on the electrophysical properties of reduced lithium niobate crystals though contact phenomena occurring during electrical conductivity measurement as well as issues of interaction between the electrode material and the test specimens are almost disregarded. The effect of chromium and indium tin oxide electrodes on the results of measurements of electrophysical parameters at room temperature for lithium niobate specimens reduced at 1100 °C has been investigated. It was found that significant nonlinearities in the VACs of the specimens at below 5 V distort the specific resistivity readings for lithium niobate. This requires measurements at higher voltages. Impedance spectroscopy studies have shown that the measurement results are largely affected by capacities including those probably induced near the contacts. It has been shown that the experimental results are described adequately well by a model implying the presence of near-contact capacities that are parallel to the specimen’s own capacity. Possible mechanism of the induction of these capacities has been described and a hypothesis has been proposed of the high density of electron states at the electrode/specimen interface that can trap carriers, the concentration of trapped carriers growing with an increase in annealing duration.
Gravité, vide, gravidité
Authors: Golse Bernard
Published: March 2022

Après avoir rappelé les principaux éléments de la dynamique psychique de la grossesse, soit la dimension d’étrangeté de l’enfant et les différentes composantes de l’enfant imaginaire, l’auteur aborde ensuite la problématique des dépressions périnatales en se référant au processus d’objectalisation progressive du fœtus. La réflexion aborde ainsi les deux pôles des représentations du vide et du vide de représentations qui renvoient différemment au concept de gravité. Qu’il s’agisse de dépressions maternelles pré ou postnatales, la nature de la perte d’objet pose la question d’une troisième topique qui distinguerait la place de l’objet, les liens à l’objet et l’objet en tant que tel, en donnant à la représentation des liens une place centrale ouvrant sur une possible métapsychologie périnatale.

À partir de séquences cliniques, nous tenterons de discuter la manière dont le hamac est venu s’affirmer comme un point d’attraction des enjeux thérapeutiques d’un groupe d’enfants en cmpp . Engageant des processus symboliques et sensori-moteurs, les jeux développés à partir du hamac ont permis aux enfants du groupe de revisiter des étapes du développement plus archaïques sur lesquelles la fonction mytho-poéïtique a pu s’inscrire. Nous interrogerons par ce biais les rapports entretenus par les fonctions phoriques et métaphoriques dans ce groupe.
