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…
Variability Survey in the Open Cluster Stock 14 and the Surrounding Fields
D. Drobek, A. Pigulski, R. R. Shobbrook +1
We present the results of a photometric variability survey in the young open cluster Stock 14 and the surrounding fields. In total, we detected 103 variable stars of which 88 are n…
Pulsating stars in NGC 6231 Frequency analysis and photometric mode identification near the main sequence
Stefan Meingast, Gerald Handler, Robert R. Shobbrook
We used Johnson UBV photometric CCD observations to identify pulsating and other variable stars in the young open cluster NGC 6231. The multi-color information was used to classify…
A multisite photometric study of two unusual Beta Cep stars: the magnetic V2052 Oph and the massive rapid rotator V986 Oph
G. Handler, R. R. Shobbrook, K. Uytterhoeven +15
We report a multisite photometric campaign for the Beta Cep stars V2052 Oph and V986 Oph. 670 hours of high-quality differential photoelectric Stromgren, Johnson and Geneva time-se…
Starspots on the fastest rotators in the Beta Pic moving group
D. Garcia-Alvarez, A. F. Lanza, S. Messina +7
Aims: We carried out high-resolution spectroscopy and BV(I)_C photometric monitoring of the two fastest late-type rotators in the nearby Beta Pictoris moving group, HD199143 (F7V)…
Photometric Observations of Three High Mass X-Ray Binaries and a Search for Variations Induced by Orbital Motion
Gordon E. Sarty, Bogumil Pilecki, Daniel E. Reichart +8
We searched for long period variation in V-band, Ic-band and RXTE X-ray light curves of the High Mass X-ray Binaries (HMXBs) LS 1698 / RX J1037.5-5647, HD 110432 / 1H 1249-637 and…
