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…

Probing down to early cosmic epochs using limited redshift () optical surveys with host galaxy age and lookback time analysis

Siddharth Kasthurirangan, Meet Panchal, Aparna Joshi +1

We present a detailed analysis of AGN identification diagnostics and host galaxy evolution using optical spectral diagnostics using ESO-GOODS-S data. We employ traditional Baldwin-…

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. I…

Adding TESS to CRÉME. Light curves and masses of 300+ eclipsing binaries

Krzysztof G. Hełminiak, Ayush Moharana, Tilak B. Pawar +1

The Comprehensive Research with Echelles on the Most interesting Eclipsing binaries (CRÉME) 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…

Comprehensive study of five candidate delta Scuti-type pulsators in detached eclipsing binaries

T. Pawar, K. G. Hełminiak, 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…
