Optical Photometry of GRB 021004: The First Month
Stephen T. Holland, Michael Weidinger, Johan P. U. Fynbo +17
We present U,B,V,R_C,and I_C photometry of the optical afterglow of the gamma-ray burst GRB 021004 taken at the Nordic Optical Telescope between approximately eight hours and 30 da…
Absorption Systems in the Spectrum of GRB 021004
P. Møller, J. P. U. Fynbo, J. Hjorth +10
We report on a 3600 s spectrum of GRB 021004 obtained with the Nordic Optical Telecope on La Palma 10.71 hours after the burst. We identify absorption lines from five systems at re…
The Afterglow of GRB010222: A Case of Continuous Energy Injection
G. Bjornsson, J. Hjorth, K. Pedersen +1
The optical lightcurve of GRB010222 exhibited one of the slowest decays of any gamma-ray burst to date. Its broadband properties have been difficult to explain with conventional af…
Evidence for Solar-like Oscillations in Arcturus (Alpha Boo)
Alon Retter, Timothy R. Bedding, Derek Buzasi +1
Observations of the red giant Arcturus (Alpha Boo) obtained with the star tracker on the Wide Field Infrared Explorer (WIRE) satellite during a baseline of 19 successive days in 20…
White Dwarf Seismology and the ^{12}C(alpha,gamma)^{16}O Rate
Travis S. Metcalfe
Recent determinations of the internal composition and structure of two helium-atmosphere variable white dwarf stars, GD 358 and CBS 114, have led to conflicting implied rates for t…
Building the bridge between Damped Ly-alpha Absorbers and Lyman Break galaxies
J. P. U. Fynbo, C. Ledoux, P. Moller +3
In 2000, we started the program ``Building the Bridge between Damped Ly-alpha Absorbers and Lyman-Break Galaxies: Ly-alpha Selection of Galaxies'' at the European Southern Observat…
