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 on…
Curve of Growth Analysis of SZ Lyn
Janaka Adassuriya, Shashikiran Ganesh, Peter de Cat +2
We present one high-resolution and a time series of 561 low-resolution follow-up spectroscopic observations of SZ Lyn. It is a high-amplitude Delta Scuti-type pulsating star in a b…
On the Existence of "Maia variables"
F. Kahraman Aliçavuş, G. Handler, S. Chowdhury +5
There are different classes of pulsating stars in the H-R diagram. While many of those classes are undisputed, some remain a mystery such as the objects historically called "Maia v…
Amplitude Modulation in a Delta Scuti star HD118660
Mrinmoy Sarkar, Santosh Joshi, Peter de Cat
In this paper, we report the detection of amplitude modulation in a delta Scuti star HD118660. We found that the p-mode frequency at 24.3837 c/d varies periodically in amplitude wi…
