DW Cancri: a magnetic VY Scl star with an orbital period of 86 minutes
P. Rodriguez-Gil, B. T. Gaensicke, S. Araujo-Betancor +1
We present the first time-resolved spectroscopic study of the cataclysmic variable DW Cancri. We have determined an orbital period of 86.10 +- 0.05 min, which places the system ver…
Rapid Variations of Narrow Absorption Line Components in the Spectrum of P Cygni
Cornelis de Jager, Garik Israelian
We report the detection of rapid wavelength and intensity variations of narrow components in absorption line profiles of the hot galactic supergiant P Cygni. During most of the tim…
Narrow band survey for intragroup light in the Leo HI cloud. Constraints on the galaxy background contamination in imaging surveys for intracluster planetary nebulae
Nieves Castro-Rodriguez, J. Alfonso L. Aguerri, Magda Arnaboldi +4
We have observed emission line objects located in a 0.26 deg^2 field in the M96 (Leo) group, coincident with the intergalactic HI cloud. The emission line objects were selected usi…
Rotation of Hot Horizontal Branch Stars in Galactic Globular Clusters
A. Recio-Blanco, G. Piotto, A. Aparicio +1
We present high resolution UVES+VLT spectroscopic observations of 61 stars in the extended blue horizontal branches of the Galactic globular clusters NGC 1904 (M79), NGC 2808, NGC…
Discovery of variable circular polarization from the remnant of Nova Chamaeleontis 1953 (RR Cha)
P. Rodriguez-Gil, S. B. Potter
We report on the discovery of variable circular polarization from the remnant of Nova Chamaeleontis 1953 (RR Cha). The circular polarization appears to be modulated on the primary'…
