Chemical abundances and doppler imaging of the Ap Si/He-wk star HD 100357

Athul Dileep, Santosh Joshi, Sofya Alexeeva +11

We present the results of time-resolved photometry, abundance analysis and Doppler imaging of an Ap star, HD 100357. The {\it TESS} photometry revealed rotational modulation with a…

Unveiling the Variability and Chemical Composition of AL Col

Surath C. Ghosh, Santosh Joshi, Samrat Ghosh +9

Using \tess\ short-cadence (120\,s) SAP flux, we identified a rotational frequency of 0.09655\, (\,d). Wavelet analysis reveals that while…

Investigating Pulsating Variables and Eclipsing Binaries in NGC 2126 using Ground and Space-based Photometry, Astrometry, Spectroscopy and Modeling

Athul Dileep, Santosh Joshi, Sneh Lata +12

Pulsating variables are prevalent in the classical δ Scuti instability strip of intermediate-age open star clusters. The cluster membership of these stars facilitates a comparative…

TESS Exploration of Targets Investigated for the Nainital-Cape Survey Project

Athul Dileep, Santosh Joshi, Donald Wayen Kurtz

The Nainital-Cape Survey was initiated more than two decades ago aiming to search for and study the pulsational variability in two subclasses of chemically peculiar (CP) stars, nam…
