Heavenly metal: A study of neutron-capture element abundances in metal-poor galactic halo stars.
Burris, Debra Leigh. (1998)New abundances for neutron-capture elements in a large sample of metal-poor giants from the Bond survey in addition to 3 well known individual cases, are presented. The spectra for the Bond Giants were acquired with the ... -
Multiwavelength analyses of a small sample of nearby spiral galaxies: The radio and X-ray connection.
Maddox, Larry Allen. (2006)Included is a preliminary report on radio analyses of M101 and NGC 3184. The deep radio observations of M101 yield 28 compact radio sources. A shorter set of observations for NGC 3184 yield the detection of 10 radio sources. ... -
A radio and x-ray search for intermediate-age supernovae: Tuning into the oldies.
Stockdale, Christopher John. (2001)Type II supernovae (SNe) are the cataclysmic and very luminous last stage in the evolutionary track of very high mass stars, resulting in the destruction of the star and the ejection of large amounts of material into their ... -
"'Tis something, nothing", a search for radio supernovae.
Eck, Christopher Ronald. (1998)We report VLA radio observations of 29 SNe with ages ranging from 10 days to about 90 years past explosion. Included are detections of known radio SNe 1950B, 1957D, 1970G, 1983N, the suspected radio SN 1923A, and the ...
