Testing Rotational Mixing Predictions with New Boron Abundances in Main Sequence B-type Stars
J. T. Mendel, K. A. Venn, C. R. Proffitt +2
(Abridged) New boron abundances for seven main-sequence B-type stars are determined from HST STIS spectroscopy around the BIII 2066A line. Boron abundances provide a unique and cri…
Limits on the Optical Brightness of the Epsilon Eridani Dust Ring
Charles Proffitt, Kailash Sahu, Mario Livio +10
The STIS/CCD camera on the {\em Hubble Space Telescope (HST)} was used to take deep optical images near the K2V main-sequence star Eridani in an attempt to find an optical coun…
The Ionized Gas in Local Starburst Galaxies: Global and Small--Scale Feedback from Star Formation
Daniela Calzetti, Jason Harris, John S. Gallagher +4
Abridged: The small-- and intermediate--scale structure and the fraction of the ISM ionized by non--radiative processes is investigated in a small sample of four local starburst ga…
The Recent Cluster Formation Histories of NGC 5253 and NGC 3077: Environmental Impact on Star Formation
J. Harris, D. Calzetti, J. S. Gallagher +2
We present multicolor photometry of bright star cluster candidates in the nearby starburst galaxies NGC 3077 and NGC 5253, observed with the Hubble Space Telescope Wide Field and P…
Kinematics of Ten Early-Type Galaxies from HST and Ground-Based Spectroscopy
Jason Pinkney, Karl Gebhardt, Ralf Bender +11
We present stellar kinematics for a sample of 10 early-type galaxies observed using the STIS aboard the Hubble Space Telescope, and the Modular Spectrograph on the MDM Observatory…
X-ray and Optical Variations in the Classical Be Star gamma Cas
Richard D. Robinson, Myron A. Smith, Gregory W. Henry
gamma Cas (B0.5e) is known to be a unique X-ray source because ot its moderate L_x, hard X-ray spectrum, and light curve punctuated by ubiquitous flares and slow undulations. Its X…
