Halo Star Streams in the Solar Neighborhood
Amanda A. Kepley, Heather L. Morrison, Amina Helmi +6
We have assembled a sample of halo stars in the solar neighborhood to look for halo substructure in velocity and angular momentum space. Our sample includes red giants, RR Lyrae, a…
The UV Scattering Halo of the Central Source Associated with Eta Carinae
D. John Hillier, T. Gull, K. Nielsen +8
We have made an extensive study of the UV spectrum of Eta Carinae, and find that we do not directly observe the star and its wind in the UV. Because of dust along our line of sight…
On the He II Emission In Eta Carinae and the Origin of Its Spectroscopic Events
J. C. Martin, K. Davidson, R. M. Humphreys +2
We describe and analyze Hubble Space Telescope (HST) observations of transient emission near 4680 Å in Eta Car, reported earlier by Steiner & Damineli (2004). If, as seems probable…
A Change in the Physical State of Carinae?
K. Davidson, J. C. Martin, R. M. Humphreys +8
During Car's spectroscopic event in mid-2003, the stellar wind's bright H and H emission lines temporarily had a distinctive shape unlike that reported on any previous oc…
The Masses Of The B-Stars In The High Galactic Latitude Eclipsing Binary IT Lib
John C. Martin
A number of blue stars which appear to be similar to Population I B-stars in the star forming regions of the galactic disk are found more than 1 kpc from the galactic plane. Uncert…
