MULTIWAVELENGTH MONITORING OF THE DWARF SEYFERT 1 GALAXY NGC 4395. I. A REVERBERATION-BASED MEASUREMENT OF THE BLACK HOLE MASS
A reverberation-mapping program on NGC 4395, the least luminous known Seyfert 1 galaxy, undertaken with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope yields a measurement ofExpand

The radial velocity experiment (RAVE): First data release
TLDR
We present the first data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities and stellar atmosphere parameters (temperature, metallicity, and surface gravity) of up to one million stars using the Six Degree Field multiobject spectrograph on the Anglo-Australian Observatory.

PLANETARY CONSTRUCTION ZONES IN OCCULTATION: DISCOVERY OF AN EXTRASOLAR RING SYSTEM TRANSITING A YOUNG SUN-LIKE STAR AND FUTURE PROSPECTS FOR DETECTING ECLIPSES BY CIRCUMSECONDARY AND CIRCUMPLANETARY
The large relative sizes of circumstellar and circumplanetary disks imply that they might be seen in eclipse in stellar light curves. We estimate that a survey of ~104 young (~10 million year old)Expand

The Frequency of Barred Spiral Galaxies in the Near-Infrared*
We have determined the fraction of barred galaxies in the H-band for a statistically well-defined sample of 186 spirals drawn from the Ohio State University Bright Spiral Galaxy Survey. We find 56%Expand

Spectral energy distributions of Seyfert nuclei
We present nuclear spectral energy distributions (SEDs) in the range 0.4-16 lm for an expanded CfA sample of Seyfert galaxies. The spectral indexes (f� / � � � IR) from 1 to 16 lm range fromIR � 0.9Expand

Predictions for a planet just inside Fomalhaut's eccentric ring
We propose that the eccentricity and sharpness of the edge of Fomalhaut’s disk are due to a planet just interior to the ring edge. The collision timescale consistent with the disk opacity is longExpand

Structure in the Eridani Dusty Disk Caused by Mean Motion Resonances with a 0.3 Eccentricity Planet at Periastron
The morphology of the Eridani dust ring is reproduced by a numerical simulation of dust particles captured into the 5 : 3 and 3 : 2 exterior mean motion resonances with a 0.3 eccentricity 10-4 M☉Expand

Sagittarius A* Companion S0-2: A Probe of Very High Mass Star Formation
The star S0-2, which is orbiting Sgr A* with a 15 yr period, almost certainly did not form in situ. We propose that it was injected into this close orbit by the tidal disruption of a massive-starExpand

Near-Infrared and Optical Morphology of Spiral Galaxies
We announce the initial release of data from the Ohio State University (OSU) Bright Spiral Galaxy Survey, a BVRJHK imaging survey of a well-defined sample of 205 bright, nearby spiral galaxies. WeExpand

The Multitude of Unresolved Continuum Sources at 1.6 Microns in Hubble Space Telescope Images of Seyfert Galaxies
We examine 112 Seyfert galaxies observed by the Hubble Space Telescope at 1.6 km. We —nd that D50% of the Seyfert 2.0 galaxies which are part of the Revised Shapely-Ames (RSA) Catalog or the CfAExpand
