IRAS 09002-4732: A Laboratory for the Formation of Rich Stellar Clusters
Astronomical Journal - Tập 158 Số 6 - Trang 235 - 2019
Konstantin V. Getman, E. D. Feigelson, Michael A. Kuhn, Patrick S. Broos, G. P. Garmire
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
The TESS Input Catalog and Candidate Target List

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

pyLIMA: An Open-source Package for Microlensing Modeling. I. Presentation of the Software and Analysis of Single-lens Models
Astronomical Journal - Tập 154 Số 5 - Trang 203 - 2017
E. Bachelet, M. Norbury, V. Bozza, R. A. Street
Abstract Microlensing is a unique tool, capable of detecting the “cold” planets between ∼1 and 10 au from their host stars and even unbound “free-floating” planets. This regime has been poorly sampled to date owing to the limitations of alternative planet-finding methods, but a watershed in discoveries is anticipated in the near future thanks to the ...... hiện toàn bộ
UKIRT MICROLENSING SURVEYS AS A PATHFINDER FOR WFIRST: THE DETECTION OF FIVE HIGHLY EXTINGUISHED LOW- EVENTS
Astronomical Journal - Tập 153 Số 2 - Trang 61 - 2017
Yossi Shvartzvald, G. Bryden, Andrew Gould, A. Gould, Steve B. Howell, Charles Beichman
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
