Using Cepheids to determine the galactic abundance gradient I. The solar neighbourhood
S. M. Andrievsky, V. V. Kovtyukh, R. E. Luck +7
A number of studies of abundance gradients in the galactic disk have been performed in recent years. The results obtained are rather disparate: from no detectable gradient to a rat…
The Solar Neighborhood VI: New Southern Stars Identified by Optical Spectroscopy
Todd J. Henry, Lucianne M. Walkowicz, Todd C. Barto +1
Broadband optical spectra are presented for 34 known and candidate nearby stars in the southern sky. Spectral types are determined using a new method that compares the entire spect…
The Relationship Between Masers and Massive Star Formation: What Can Be Learned from the Infrared?
J. M. De Buizer
The infrared represents an alternative wavelength regime in which to study the environments of maser emission, while at the same time complementing the information obtained through…
Kinematics of the HH 111 jet from STIS spectra
A. C. Raga, A. Noriega-Crespo, B. Reipurth +4
We present a long-slit spectrum of the Herbig-Haro object HH 111, obtained with SITS on the Hubble Space Telescope. This spectrum has a spectral resolution of approx. 50 km/s, so i…
The HI Environment of Three Superbubbles in the Large Magellanic Cloud
M. S. Oey, B. Groves, L. Staveley-Smith +1
The ambient interstellar environment of wind- and supernova-driven superbubbles strongly affects their evolution, but its properties are rarely well-determined. We have therefore o…
The WARPS Survey: VI. Galaxy Cluster and Source Identifications from Phase I
E. S. Perlman, D. J. Horner, L. R. Jones +4
We present in catalog form the optical identifications for objects from the first phase of the Wide Angle ROSAT Pointed Survey (WARPS). WARPS is a serendipitous survey of relativel…
