HD 210111: a new lambda Bootis type SB system
E. Paunzen, U. Heiter, L. Fraga +1
The small group of lambda Bootis stars comprises late B to early F-type stars, with moderate to extreme (up to a factor 100) surface underabundances of most Fe-peak elements and so…
He II 4686 in eta Carinae: collapse of the wind-wind collision region during periastron passage
M. Teodoro, A. Damineli, J. I. Arias +23
The periodic spectroscopic events in eta Carinae are now well established and occur near the periastron passage of two massive stars in a very eccentric orbit. Several mechanisms h…
Star Formation in the Gulf of Mexico
Tina Armond, Bo Reipurth, John Bally +1
We present an optical/infrared study of the dense molecular cloud, L935, dubbed "The Gulf of Mexico", which separates the North America and the Pelican nebulae, and we demonstrate…
GALEX and Optical Observations of GW Librae During the Long Decline from Superoutburst
Eric Bullock, Paula Szkody, Anjum S. Mukadam +14
The prototype of accreting, pulsating white dwarfs (GW Lib) underwent a large amplitude dwarf nova outburst in 2007. We used ultraviolet data from GALEX and ground-based optical ph…
