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. HeÅminiak +4
Eclipsing double-lined spectroscopic binaries hosting Scuti-type pulsators offer a unique laboratory for simultaneously constraining stellar geometry and interior structure. I…
Adding TESS to CRÃME. Light curves and masses of 300+ eclipsing binaries
Krzysztof G. HeÅminiak, Ayush Moharana, Tilak B. Pawar +1
The Comprehensive Research with Echelles on the Most interesting Eclipsing binaries (CRÃME) projects was aimed to collect high-resolutions spectra of about 380 detached eclipsing…
Formation of Compact Hierarchical Triples
Ayush Moharana, K. G. Helminiak, T. Pawar +1
Compact hierarchical triples (CHTs) are triple stars where the tertiary is in an orbit of a period less than 1000 d. They were thought to be rare but we are discovering more of the…
High-resolution spectroscopy of detached eclipsing binaries during total eclipses
Krzysztof G. HeÅminiak, Justyna Olszewska, Maria Puciata-Mroczynska +1
We present results of high-resolution spectroscopic observations of detached eclipsing binaries (DEBs) with total eclipses, for which UVES spectra were obtained during the phase of…
Comprehensive study of five candidate delta Scuti-type pulsators in detached eclipsing binaries
T. Pawar, K. G. HeÅminiak, A. Moharana +4
Pulsating stars in eclipsing binaries (EBs) provide an excellent opportunity to obtain precise, model-independent stellar parameters for studying oscillations in detail. One common…
