Automated eccentricity measurement from raw eclipsing binary light curves with intrinsic variability
Luc W. IJspeert, Andrew Tkachenko, Cole Johnston +3
Abstract abridged. Eclipsing binary systems provide the opportunity to measure the fundamental parameters of their component stars in a stellar-model-independent way. This makes th…
Identifying and characterising the population of hot sub-luminous stars with multi-colour MeerLICHT data
P. Ranaivomanana, C. Johnston, P. J. Groot +9
Colour-magnitude diagrams reveal a population of blue (hot) sub-luminous objects with respect to the main sequence. These hot sub-luminous stars are the result of evolutionary proc…
Tidal perturbations and eclipse mapping in the pulsations in the hierarchical triple system U~Gru
Cole Johnston, Andrew Tkachenko, Timothy Van Reeth +4
Context. Unambiguous examples of the influence of tides on self-excited, free stellar pulsations have recently been observationally detected in space-based photometric data. Aims.…
Planet Hunters TESS IV: A massive, compact hierarchical triple star system TIC 470710327
Nora L. Eisner, Cole Johnston, Silvia Toonen +37
We report the discovery and analysis of a massive, compact, hierarchical triple system (TIC 470710327) initially identified by citizen scientists in data obtained by NASA's Transit…
TESS Eclipsing Binary Stars. I. Short cadence observations of 4584 eclipsing binaries in Sectors 1-26
Andrej Prsa, Angela Kochoska, Kyle E. Conroy +44
In this paper we present a catalog of 4584 eclipsing binaries observed during the first two years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binar…
An all-sky sample of intermediate- to high-mass OBA-type eclipsing binaries observed by TESS
Luc W. IJspeert, Andrew Tkachenko, Cole Johnston +4
Context. Intermediate- to high-mass stars are the least numerous types of stars and they are less well understood than their more numerous low-mass counterparts in terms of their i…
