On the relation between supersoft X-ray sources and VY Scl stars: The cases of V504 Cen and VY Scl
J. Greiner, R. Schwarz, C. Tappert +3
We summarize our optical monitoring program of VY Scl stars with the SMARTS telescopes, and triggered X-ray as well as optical observations after/during state transitions of V504 C…
The polarization evolution of the optical afterglow of GRB 030329
J. Greiner, S. Klose, K. Reinsch +23
We report 31 polarimetric observations of the afterglow of GRB 030329 with high signal-to-noise and high sampling frequency. The data imply that the afterglow magnetic field has sm…
VLT spectroscopy of GRB 990510 and GRB 990712; probing the faint and bright end of the GRB host galaxy population
P. M. Vreeswijk, A. Fruchter, L. Kaper +15
We present time-resolved optical spectroscopy of the afterglows of the gamma-ray bursts GRB 990510 and GRB 990712. Through the identification of several absorption lines in the fir…
A Newly Discovered SU UMa-Type Dwarf Nova, HS 1449+6415
D. Nogami, D. Engels, B. T. Gaensicke +3
We report time-resolved photometric observations of the Hamburg Quasar Survey-selected dwarf nova HS 1449+6415 (= RX J1450.5+6403) during the interval from JD 2451672 to 2451724. D…
