F stars: A challenge to stellar evolution
A. A. Suchkov, S. A. Lyapustina
Many main-sequence F and early G stars are too luminous for their effective temperature, surface gravity, and chemical composition. These {\it overluminous stars} have two curious…
SDSS AGNs with X-ray Emission from ROSAT PSPC Pointed Observations
A. A. Suchkov, R. J. Hanisch, W. Voges +1
We present a sample of 1744 type 1 active galactic nuclei (AGNs) from the Sloan Digital Sky Survey (SDSS DR4) spectroscopic catalog with X-ray counterparts in the White-Giommi-Ange…
Candidate Pre-Mainsequence F Stars with Circumstellar Dust Identified Using Combined 2MASS and uvby Data
A. A. Suchkov, A. B. Schultz, C. M. Lisse
We propose a method that uses near-infrared plus uvby photometry to identify potentially extensive circumstellar dusty environment about F and A stars. The method has been applied…
The NICMOS Snapshot Survey of nearby Galaxies
T. Boeker, D. Calzetti, W. Sparks
We present ``snapshot'' observations with the NearInfrared Camera and MultiObject Spectrometer (NICMOS) on board the Hubble Space Telescope (HST) of 94 nearby galaxies from the Rev…
