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…
Functional relationships for and log~ in F-G supergiants from photometry
A. Arellano Ferro
From photoelectric data and recent accurate synthetic and spectroscopic values of and log~ for 50 F-G supergiants, we have calculated functional relationsh…
uvby-beta photoelectric photometry of Cepheid stars
J. H. Peña, A. Arellano Ferro, R. Peña-Miller +9
We present time-series uvby-beta photometry of 41 classical Cepheid stars. A brief discussion of the comparison between the presented data and previous photometric data has been do…
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…
