The Delta Scuti star 38 Eri from the ground and from space
M. Paparo, Z. Kollath, R. R. Shobbrook +17
We present and discuss the pulsational characteristics of the Delta Scuti star 38 Eri from photometric data obtained at two widely spaced epochs, partly from the ground (1998) and…
Searching for short-period variable stars in the direction of Coma Berenices and Upgren 1 open clusters: Melotte 111 AV 1224 a new eclipsing binary star
L. Fox Machado, R. Michel, M. Alvarez +1
We report the results of CCD photometric observations in the direction of the Coma Berenices and Upgren 1 open clusters with the aim at searching for new short-period variable star…
Characterizing the variability of Melotte 111 AV 1224: a new variable star in the Coma Berenices open cluster
L. Fox-Machado, R. Michel, M. Alvarez +1
A search for new pulsating stars in the Coma Berenices open cluster was carried out. As a result of this search the cluster member Melotte 111 AV 1224 presented clear indications o…
Physical parameters of three field RR Lyrae stars
A. Arellano Ferro, J. H. Pena, R. Figuera Jaimes
Strömgren photometry of the stars classified as RR Lyrae stars RU Piscium, SS Piscium and TU Ursae Majoris has been used to estimate their iron abundance, temperature, gra…
Determination of the physical characteristics of the variable stars in the direction of the open cluster NGC 6811 through photoelectric photometry
J. H. Peña, L. Fox-Machado, H. García +4
The study of open clusters and their short period variable stars is fundamental in stellar evolution. Because the cluster members are formed in almost the same physical conditions,…
photoelectric photometry of the open clusters NGC 6811 and NGC 6830
J. H. Pena, L. Fox Machado, H. Garcia +4
From photometry of the open clusters NGC 6811 (75 stars), and NGC 6830 (19 stars) we were able to determine membership of the stars to each cluster, and fix the age and re…
