CCD time-series photometry of the globular cluster NGC 6981: Variable star census and physical parameter estimates
D. M. Bramich, R. Figuera Jaimes, Sunetra Giridhar +1
We present the results from 10 nights of observations of the globular cluster NGC 6981 (M72) in the V, R and I Johnson wavebands. We employed the technique of difference image anal…
Advances in Spectral Classification

In this article we give an overview of the developments in the field of spectral classification and its continued importance in the fields of stellar and galactic evolution. The ex…
Chemical composition of A--F type post-AGB candidates
Sunetra Giridhar, R. Molina, A. Arellano Ferro +1
An abundance analysis has been conducted for a sample of nine post-AGB candidate stars; eight of them have not been explored before. We find four very promising objects like HD 105…
Spectral Classification; Old and Contemporary
Sunetra Giridhar
Beginning with a historical account of the spectral classification, its refinement through additional criteria is presented. The line strengths and ratios used in two dimensional c…
