Tight stellar binaries favour active longitudes at sub- and anti-stellar points
Ritika Sethi, David V. Martin
Stellar binaries are ubiquitous in the galaxy and a laboratory for astrophysical effects. We use TESS to study photometric modulations in the lightcurves of 162 unequal mass eclips…

A deep study of open cluster NGC 5288 using photometric and astrometric data from Gaia DR3 and 2MASS
Ritika Sethi, D. Bisht, Geeta Rangwal +1
This paper investigates a poorly studied open cluster, NGC 5288, using 2MASS JHKS and the recently released Gaia DR3 astrometric and photometric data. The mean proper motions in Ri…

Revised Temperatures For Two Benchmark M-dwarfs -- Outliers No More
David V. Martin, Tayt Armitage, Alison Duck +7
Well-characterised M-dwarfs are rare, particularly with respect to effective temperature. In this letter we re-analyse two benchmark M-dwarfs in eclipsing binaries from Kepler/K2:…
