SN 1993J VLBI (III): The Evolution of the Radio Shell
M. F. Bietenholz, N. Bartel, M. P. Rupen
We present two sequences of VLBI images of SN1993J in M81, with 24 images at 8.4 GHz and 19 images at 5.0 GHz, These sequences, from 50 d to ~9 yr after shock breakout, show the ev…
Uncovering Additional Clues to Galaxy Evolution. II. The Environmental Impact of the Virgo Cluster on the Evolution of Dwarf Irregular Galaxies
Henry Lee, Marshall L. McCall, Michael G. Richer
The impact of the cluster environment on the evolution of dwarf galaxies is investigated by comparing the properties of a sample of dwarf irregulars (dIs) in the Virgo Cluster with…
Nebular Abundances of Nearby Southern Dwarf Galaxies
Henry Lee, Eva K. Grebel, Paul Hodge
The results of optical spectroscopy of H II regions in a sample of southern dwarf irregulars consisting of five dwarf galaxies in the Centaurus A group, four dwarfs in the Sculptor…
The Extinction and Distance of Maffei 1
Robin L. Fingerhut, Marshall L. McCall, Michael De Robertis +4
We have obtained low- and high-resolution spectra of the core of the highly-reddened elliptical galaxy Maffei 1. From these data, we have obtained the first measurement of the Mg2…
VLBI imaging of the RS CVn binary star system HR 5110
R. R. Ransom, N. Bartel, M. F. Bietenholz +4
We present VLBI images of the RS CVn binary star HR 5110 (=BH CVn; HD 118216), obtained from observations made at 8.4 GHz on 1994 May 29/30 in support of the NASA/Stanford Gravity…
