Short-term Hα line variations in Classical Be stars: 59 Cyg and OT Gem
Paul KT, Shruthi S Bhat, Annapurni Subramaniam
We present the optical spectroscopic study of two Classical Be stars, 59 Cyg and OT Gem obtained over a period of few months in 2009. We detected a rare triple-peak H emission p…
How much can we trust high-resolution spectroscopic stellar chemical abundances?
S. Blanco-Cuaresma, T. Nordlander, U. Heiter +8
To study stellar populations, it is common to combine chemical abundances from different spectroscopic surveys/studies where different setups were used. These inhomogeneities can l…
How much can we trust high-resolution spectroscopic stellar atmospheric parameters?
S. Blanco-Cuaresma, T. Nordlander, U. Heiter +8
The determination of atmospheric parameters depends on the use of radiative transfer codes (among other elements such as model atmospheres) to compute synthetic spectra and/or deri…
The Nainital-Cape Survey-IV
Santosh Joshi, P. Martinez, Sowgata Chowdhury +6
The Nainital-Cape survey is a dedicated ongoing survey programme to search for and study pulsational variability in chemically peculiar (CP) stars to understand their internal stru…
Spectroscopic study of Be-shell stars: 4 Her and 88 Her
Bhat S Shruthi, K T Paul, Subramaniam Annapurni +1
We present the optical spectroscopic study based on 41 spectra of 4 Her and 32 spectra of 88 Her, obtained over a period of 6 months. We estimate the rotational velocity of these s…
