Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
Physics of Eclipsing Binaries. V. General Framework for Solving the Inverse Problem
Kyle E Conroy, Angela Kochoska, Daniel Hey +6
PHOEBE 2 is a Python package for modeling the observables of eclipsing star systems, but until now has focused entirely on the forward-model -- that is, generating a synthetic mode…
Spectroscopic patch model for massive stars using PHOEBE II and FASTWIND
Michael Abdul-Masih, Hugues Sana, Kyle E. Conroy +4
Massive stars play an important role in the mechanical and chemical evolution of galaxies. Understanding the internal processes of these stars is vital to our understanding of thei…
Physics of Eclipsing Binaries. IV. The impact of interstellar extinction on the light curves of eclipsing binaries
David Jones, Kyle E. Conroy, Martin Horvat +6
Traditionally, the effects of interstellar extinction on binary star light curves have been treated as a uniform reduction in the observed brightness of the system that is independ…
Physics of Eclipsing Binaries. III. Spin-Orbit Misalignment
Martin Horvat, Kyle E. Conroy, Herbert Pablo +4
Binary systems where the axis of rotation (spin) of one or both components is tilted w.r.t. the axis of revolution are called misaligned binary systems. The angle of misalignment,…
