Unravelling Mass Transfer in Algols from Surface Abundances. I. Z Vulpeculae
Ahmet DerviÅoÄlu, Ahmet Dervişoğlu, Simge Adalalı +13
The photospheric abundance pattern of the components is a sensitive probe of mass and angular momentum transfer in Algols. With the aim to trace the evolutionary history and disclo…
High-precision K2/TESS Photometry and HERMES Spectroscopy of Four Bright Field Stars
Otto Trust, Santosh Joshi, Benard Nsamba +13
Space-based photometry from K2 and TESS, coupled with high-resolution spectroscopy, provides a unique opportunity to re-examine the variability and chemical nature of four bright s…
Asteroseismology of HD 23734, HD 68703, and HD 73345 using K2-TESS Space-based Photometry and High-resolution Spectroscopy
Santosh Joshi, Athul Dileep, Eugene Semenko +14
In this paper, we present a comprehensive study of three stars, HD 23734, HD 68703, and HD 73345, which were previously observed as chemically peculiar candidates within the Nainit…
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 comparativ…
Asteroseismology of the mild Am Sct star HD 118660 : TESS photometry and modelling
Mrinmoy Sarkar, Santosh Joshi, Marc-Antoine Dupret +9
We present the results of an asteroseismic study of HD 118660 (TIC 171729860), being a chemically peculiar (mild Am) star exhibiting Scuti ( Sct) pulsations. It is based o…
