Observations of the pulsating subdwarf B star Feige 48: Constraints on evolution and companions
M. D. Reed, S. D. Kawaler
Since pulsating subdwarf B (sdBV or EC14026) stars were first discovered (Kilkenny et al, 1997), observational efforts have tried to realize their potential for constraining the in…
Amplitude and frequency variability of the pulsating DB white dwarf stars KUV 05134+2605 and PG 1654+160 observed with the Whole Earth Telescope
G. Handler
We have acquired new time series photometry of the two pulsating DB white dwarf stars KUV 05134+2605 and PG 1654+160 with the Whole Earth Telescope. Additional single-site photomet…
An Early-Time Infrared and Optical Study of the Type Ia Supernova 1998bu in M96
M. Hernandez, W. P. S. Meikle, A. Aparicio +22
We present first-season infrared (IR) and optical photometry and spectroscopy of the Type Ia Supernova 1998bu in M96. We also report optical polarimetry of this event. SN1998bu is…
The excitation and kinematical properties of H2 and [FeII] in the HH46/47 bipolar outflow
Amadeu Fernandes
Long slit spectra of the molecular outflow Herbig-Haro (HH) 46/47 has been taken in the J and K near-infrared bands. The observed H2 line emission confirms the existence of a brigh…
Early detection of the optical counterpart to GRB 980329
J. Gorosabel, A. J. Castro-Tirado, A. Pedrosa +6
We report optical observations of the GRB 980329 error box which represent the second earliest detection of the GRB 980329 optical transient. We determine R = 23.7 0.5 mag on…
