Discovery of A New Class of Pulsating Stars: Gravity-mode Pulsators among Subdwarf B Stars
E. M. Green, G. Fontaine, M. D. Reed +15
During the course of an ongoing CCD monitoring program to investigate low-level light variations in subdwarf B (sdB) stars, we have serendipitously discovered a new class of low am…
The time delay of the quadruple quasar RX J0911.4+0551
Jens Hjorth, Ingunn Burud, Andreas O. Jaunsen +9
We present optical lightcurves of the gravitationally lensed components A (=A1+A2+A3) and B of the quadruple quasar RX J0911.4+0551 (z = 2.80). The observations were primarily obta…
An optical time-delay estimate for the double gravitational lens system B1600+434
I. Burud, J. Hjorth, A. O. Jaunsen +7
We present optical I-band light curves of the gravitationally lensed double QSO B1600+434 from observations obtained at the Nordic Optical Telescope (NOT) between April 1998 and No…
Evidence for Diverse Optical Emission from Gamma-Ray Burst Sources
H. Pedersen, A. O. Jaunsen, T. Grav +25
Optical Transients from gamma-ray burst sources, in addition to offering a distance determination, convey important information on the physics of the emission mechanism, and perhap…
