A Study on the Kinematics of the HII Regions of NGC 4449
We have used the TAURUS Fabry-Perot imaging spectrograph at the William Hershell Telescope of the Observatorio del Roque de los Muchachos to study the...
A suite of community tools for spectro-polarimetric analysis .
The National Center for Atmospheric Research (NCAR) has undertaken a 3-year initiative to develop the Community Spectro-polarimetric Analysis Center (CSAC). The...
A summary of solar 1-8A measurements from the SMS and GOES satellites, 1977-1981
The 1-8A band of synodic full-disc solar X-rays (1-8A) W/m(2) were measured nearly continuously from 1975 to 1981 aboard the SMS-1, SMS-2, GOES-1, GOES-2, and...
A Survey for Extrasolar Planets Around A F Type Stars
Since the discovery of the first extrasolar planet 51 Pegb [1] more than 190 extrasolar planets have been detected in orbit around other stars by means of...
We will present results of a survey of Hilda asteroids to look for extreme shape objects. We used WISE [1, 2] sparse IR photometry to identify objects with high...
We recently discovered an apparently new class of pulsating Extreme Horizontal Branch (EHB) star in ω Cen. Tightly clustered around ˜50,000 K, these H-rich sdO...
A survey of low density early-type galaxies in low density environments.
We have completed a survey of early-type galaxies in a region covering 700 sq. degrees with cz -20 that satisfy our isolation criteria. The sample galaxies obey...
