Abstract
IRAS 09002-4732 is a poorly studied embedded cluster of stars in the Vela Molecular Ridge at a distance of 1.7 kpc. Deep observations with the Chandra X-ray Observatory, combined with existing optical and infrared surveys, produce a catalog of 441 probable pre-main-sequence members of the region. The stellar spatia...... hiện toàn bộ

Abstract
The Transiting Exoplanet Survey Satellite (TESS) will be conducting a nearly all-sky photometric survey over two years, with a core mission goal to discover small transiting exoplanets orbiting nearby bright stars. It will obtain 30 minute cadence observations of all objects in the ... hiện toàn bộ

UKIRT MICROLENSING SURVEYS AS A PATHFINDER FOR WFIRST: THE DETECTION OF FIVE HIGHLY EXTINGUISHED LOW- EVENTSAstronomical Journal - Tập 153 Số 2 - Trang 61 - 2017

ABSTRACT
Optical microlensing surveys are restricted from detecting events near the Galactic plane and center, where the event rate is thought to be the highest due to the high optical extinction of these fields. In the near-infrared (NIR), however, the lower extinction leads to a corresponding increase in event detections and is a primary driver for...... hiện toàn bộ
