Cool Gas and Massive Stars: The Nuclear Ring in M100
The SAURON integral-field spectrograph was used to observe the central area of the barred spiral galaxy M100 (NGC 4321). M100 contains a nuclear ring of star...
Cool stars in the Galactic center as seen by APOGEE. M giants, AGB stars, and supergiant stars and candidates
The Galactic center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and...
Cool White Dwarfs Found in the UKIRT Infrared Deep Sky Survey
We present the results of a search for cool white dwarfs in the United Kingdom InfraRed Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Large Area Survey...
Cool White Dwarfs Identified in the Second Data Release of the UKIRT Infrared Deep Sky Survey
We have paired the second data release of the Large Area Survey of the UKIRT Infrared Deep Sky Survey with the fifth data release of the Sloan Digital Sky...
Cooled instrumentation for infrared astronomical investigations from space
A brief review is presented of infrared astronomical instrumentation which has been proposed or accepted for observations from space platforms. Some stress is...
Cooling of the quasi-persistent neutron star X-ray transients KS 1731-260 and MXB 1659-29
We present Chandra and XMM-Newton X-ray observations that monitor the neutron star cooling of the quasi-persistent neutron star X-ray transients KS 1731-260 and...
Coordinated Multiwavelength Observation of 3C 66A during the WEBT Campaign of 2003-2004
The BL Lac object 3C 66A was the target of an extensive multiwavelength monitoring campaign from 2003 July through 2004 April (with a core campaign from 2003...
Coordinated Observations of the Red Dwarf Flare Star EV Lac in 1993
Results of cooperative observations of the flare star EV Lac in September 1993 are presented. One of the about 30 optical flares detected was powerful enough to...
Coordinated observations of the red dwarf flare star EV Lacertae in 1991
Results of cooperative optical observations of EV Lac in September 1991 are presented. During 50 hours of photoelectric monitoring more than 40 flares were...
