Double bars might be the key mechanisms to transport gas to the very central regions of galaxies, so double-barred galaxies are key objects to better understand...
A Search for Brown Dwarfs in the Alpha Persei Cluster
We present preliminary results from a deep near-infrared survey of a ˜ 1 square degree area in the young open cluster Alpha Persei using the wide-field Omega...
A search for circumbinary planets in CoRoT eclipsing binary light curves
Several transiting circumbinary planets have been found in data of the Kepler mission [1-5]. Both CoRoT and Kepler have surveyed similar numbers of stars, and...
A Search for EHB Pulsators in the Globular Cluster NGC 6752
We describe the status of a project whose main goal is to detect variability along the extreme horizontal branch of the globular cluster NGC 6752. Based on...
A Search for Evidence of an Abundance Gradient in the Galactic Halo Based on Stars from SDSS-I DR-5
One of the classical tests of the early dynamical evolution of the Milky Way is the prediction of the monolithic collapse model (e.g., Eggen, Lynden-Bell, &...
A Search for Extreme Ultracool Objects in UKIDSS+VISTA
Brown dwarfs with thick water cloud atmospheres, ancient population III brown dwarfs, and nearby free-floating planetary mass objects are targets in our new...
A Search for Giant Planets Around Very Young Nearby Late-type Dwarfs
Very young late-type dwarfs at distances closer than 30 pc are excellent sites to provide a direct detection of extrasolar planets. The combination of youth and...
