A new so-called `gravitational loss-cone instability' in stellar systems has recently been investigated theoretically in the framework of linear perturbation theory and proved to b…
Mass-Metallicity Trends in Transiting Exoplanets from Atmospheric Abundances of HO, Na, and K
Luis Welbanks, Nikku Madhusudhan, Nicole F. Allard +3
Atmospheric compositions can provide powerful diagnostics of formation and migration histories of planetary systems. We investigate constraints on atmospheric abundances of HO,…
Lagrange-Eulerian method for numerical integration of the gas dynamics equations: parallel implementation on GPUs
Sergey Khrapov, Alexander Khoperskov, Sergey Khoperskov
We describe a new CSPH-TVD method for numerical integration of hydrodynamical equations. The method is based on combined Lagrange-Euler approaches, and it has been devoted to simul…
A new implementation of the Schwarzschild method for constructing observationally-driven dynamical models of galaxies of all morphological types
Eugene Vasiliev, Monica Valluri
We present Forstand, a new code for constructing dynamical models of galaxies with the Schwarzschild orbit-superposition method. These models are constrained by line-of-sight kinem…
The Young Suns Exoplanet Survey: Detection of a wide orbit planetary mass companion to a solar-type Sco-Cen member
A. J. Bohn, M. A. Kenworthy, C. Ginski +9
The Young Suns Exoplanet Survey (YSES) consists of a homogeneous sample of 70 young, solar-mass stars located in the Lower Centaurus-Crux subgroup of the Scorpius-Centaurus associa…
MOBSTER: Establishing a Picture of Magnetic Massive Stars as a Population
Alexandre David-Uraz, Coralie Neiner, James Sikora +12
Magnetic massive and intermediate-mass stars constitute a separate population whose properties are still not fully understood. Increasing the sample of known objects of this type w…
Magnetic OB[A] Stars with TESS: probing their Evolutionary and Rotational properties -- The MOBSTER Collaboration
A. David-Uraz, C. Neiner, J. Sikora +14
In this contribution, we present the MOBSTER Collaboration, a large community effort to leverage high-precision photometry from the Transiting Exoplanet Survey Satellite (\textit{T…
Thermodynamic Equilibrium in General Relativity
J. A. S. Lima, A. Del Popolo, A. R. Plastino
The thermodynamic equilibrium condition for a static self-gravitating fluid in the Einstein theory is defined by the Tolman-Ehrenfest temperature law, $T{\sqrt {g_{00}(x^{i})}} = c…
