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…
CCD Photometry of the Pleiades Delta Scuti Star V650 Tauri
L. Fox Machado, R. Michel, M. Alvarez +2
The preliminary results of a three-site CCD photometric campaign are reported. The Scuti variable V650 Tauri belonging to the Pleiades cluster was observed photometrically for…
Multi-site photometric campaign on the high amplitude δ Scuti star KIC 6382916
C. Ulusoy, B. UlaÅ, T. Gülmez +15
We present results of a multi-site photometric campaign on the high-amplitude \,Scuti star KIC\,6382916 in the {\it Kepler} field. The star was observed over a 85-d interval at…
A study of the photometric variability of the peculiar magnetic white dwarf WD1953-011
G. Valyavin, K. Antonyuk, S. Plachinda +14
We present and interpret simultaneous new photometric and spectroscopic observations of the peculiar magnetic white dwarf WD1953-011. The flux in the V-band filter and intensity of…
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…
