UX Men: Detached Eclipsing Binary as a Benchmark Candidate
Ganesh N. Pawar, Krzysztof G. Hełminiak, Nicola J. Miller +5
We present ultra-precise fundamental parameters for the detached eclipsing binary UX Men based on 31 TESS sectors (882 d) and radial velocities from HARPS, FEROS, CORALIE, an…
V446 Cephei: a Cep pulsator in a multiple system
A. Moharana, J. Southworth, K. Pavlovski +7
Cep stars in eclipsing binary (EB) systems give us an opportunity to put observational constraints on their structure and stellar parameters. We present a comprehensive analysi…
Finding the elusive RR Lyrae companions via speckle imaging
R. Salinas, V. Kalari, G. Hajdu +25
Despite their key role in astrophysics, the binary properties of RR Lyrae stars (RRL) remain almost completely unknown since only a single RRL is confirmed as belonging to a binary…
An in-depth study of brown dwarfs with TESS
F. Marcadon, A. Prša
The existence of a deficit of brown dwarfs (BDs) in close orbit around main-sequence stars is one of the most intriguing questions in stellar physics. This so-called BD desert may…
RX Gru: a short-period pre-main-sequence eclipsing binary with a distant circumbinary companion
F. Marcadon, A. Moharana, T. B. Pawar +4
We report the discovery of a new short-period pre-main-sequence eclipsing binary, RX Gru, orbited by a distant circumbinary companion. We characterized the system by analysing the…
A comprehensive study of Scuti-type pulsators in eclipsing binaries: oscillating eclipsing Algols
T. B. Pawar, A. Miszuda, K. G. Hełminiak +4
Eclipsing double-lined spectroscopic binaries hosting Scuti-type pulsators offer a unique laboratory for simultaneously constraining stellar geometry and interior structure. In…
Spectroscopy of Eclipsing Compact Hierarchical Triples I
Ayush Moharana, K. G. Hełminiak, F. Marcadon +6
Eclipsing Compact Hierarchical Triples (ECHTs) are systems with the tertiary star orbiting an eclipsing binary (EB) in an orbit of fewer than 1000 days. In a CHT, all three stars e…
Precision timing of eclipsing binaries from TESS full frame images. Method and performance
Frédéric Marcadon, Andrej Prša
Several hundreds of thousands of eclipsing binaries (EBs) are expected to be detected in the Transiting Exoplanet Survey Satellite (TESS) full frame images (FFIs). This represents…
Solaris photometric survey: Search for circumbinary companions using eclipse timing variations
Ayush Moharana, K. G. Hełminiak, F. Marcadon +8
Eclipse timing variations (ETV) have been a successful tool for detecting circumbinary companions to eclipsing binaries (EB). While TESS and Kepler have been prolific for ETV searc…
Detached Eclipsing Binaries in Compact Hierarchical Triples: Triple-lined systems BD+44 2258 and KIC 06525196
Ayush Moharana, K. G. Hełminiak, F. Marcadon +5
Compact Hierarchical Triples (CHT) are systems with the tertiary star orbiting the inner binary in an orbit shorter than 1000 days. CHT with an eclipsing binary as its inner binary…
Evolution and Dynamics of Tight Triple Systems
Ayush Moharana, K. G. Helminiak, F. Marcadon +2
Tight Triple Systems have stars in a hierarchical configuration with a third star orbiting the inner binary with a period of fewer than 1000 days. Such systems are important for un…
Analysis of eclipsing binaries in multiple stellar systems: the case of V1200 Centauri
F. Marcadon, K. G. Hełminiak, J. P. Marques +5
We present a new analysis of the multiple star V1200 Centauri based on the most recent observations for this system. We used the photometric observations from the Solaris network a…
Asteroseismic and orbital analysis of the triple star system HD 188753 observed by Kepler
F. Marcadon, T. Appourchaux, J. P. Marques
The NASA Kepler space telescope has detected solar-like oscillations in several hundreds of single stars, thereby providing a way to determine precise stellar parameters using aste…
Asteroseismology of solar-type stars with K2
W. J. Chaplin, M. N. Lund, R. Handberg +44
We present the first detections by the NASA K2 Mission of oscillations in solar-type stars, using short-cadence data collected during K2 Campaign\,1 (C1). We understand the asteros…
