On the nature of HD 207331: a new Delta Scuti variable
L. Fox Machado, W. J. Schuster, C. Zurita +2
While testing a Stromgren spectrophotometer attached to the 1.5-m telescope at the San Pedro Martir observatory, Mexico, a number of A-type stars were observed, one of which, HD 20…
The pulsating hot subdwarf Balloon 090100001: results of the 2005 multisite campaign
A. Baran, R. Oreiro, A. Pigulski +28
We present the results of a multisite photometric campaign on the pulsating sdB star Balloon 090100001. The star is one of the two known hybrid hot subdwarfs with both long- and sh…
On the variability of HD 170699 - a possible COROT target
M. Alvarez, J. P. Sareyan, L. Parrao +9
We present the analysis of the variability of HD 170699, a COROT star showing the characteristics of a non evolutionary Delta Scuti star with high rotational velocity. There is a c…
On the nature of Delta Scuti star HD 115520
J. H. Pena, L. Fox Machado, B. Cervantes-Sodi +7
Observing Delta Scuti stars is most important as their multi-frequency spectrum of radial pulsations provide strong constraints on the physics of the stars interior; so any new det…
CCD Photometry of Delta Scuti stars 7 Aql and 8 Aql
L. Fox Machado, R. Michel, M. Alvarez +3
As a continuation of the study of the Delta Scuti stars 7 Aql and 8 Aql; new CCD photometric data were acquired in 2007. We present a period analysis on these data that confirm the…
On the nature of Delta Scuti star HD 115520
L. Fox Machado, J. H. Pena, G. Munoz +1
As a continuation of the study of the newly found Delta Scuti star HD 115520, we present a period analysis of recently acquired photometric data covering four nights, as well as so…
