Determination of the gas-to-dust ratio in nearby dense clouds using X-ray absorption measurements
MyHa Vuong, Thierry Montmerle, Nicolas Grosso +3
We present a comparison of the gas and dust properties of the dense interstellar matter in six nearby star-forming regions (d<500 pc): rho Oph, Cha I, R CrA, IC 348, NGC 1333, and…
Realizing the potential of astrostatistics and astroinformatics
Gwendolyn Eadie, Thomas J. Loredo, Ashish A. Mahabal +12
This Astro2020 State of the Profession Consideration White Paper highlights the growth of astrostatistics and astroinformatics in astronomy, identifies key issues hampering the mat…
The Stellar Population And Origin Of The Mysterious High-Latitude Star Forming Cloud CG 12
Konstantin Getman, Eric Feigelson, Warrick Lawson +2
The mysterious high galactic latitude cometary globule CG12 has been observed with the ACIS detector on board the Chandra X-ray Observatory. We detect 128 X-ray sources; half are l…
A Simultaneous Optical and X-ray Variability Study of the Orion Nebula Cluster. I. Incidence of Time-Correlated X-ray/Optical Variations
Keivan G. Stassun, M. van den Berg, Eric Feigelson +1
We present a database of time-series photometry of the Orion Nebula Cluster obtained with two ground-based telescopes at different longitudes to provide simultaneous coverag…
X-ray Properties of Young Stars and Stellar Clusters
Eric Feigelson, Leisa Townsley, Manuel Gudel +1
Although the environments of star and planet formation are thermodynamically cold, substantial X-ray emission from 10-100 MK plasmas is present. In low mass pre-main sequence stars…
Disk Evolution in OB Associations - Deep Spitzer/IRAC Observations of IC 1795
Veronica Roccatagliata, Jeroen Bouwman, Thomas Henning +5
We present a deep Spitzer/IRAC survey of the OB association IC 1795 carried out to investigate the evolution of protoplanetary disks in regions of massive star formation. Combining…
Predictions of Transiting Exoplanet Confirmations from Rubin LSST Surveys
Suber Corley, Eric Feigelson, Claudio Caceres +2
We assess the prospects for exoplanet transit observations in the 10-year Wide Fast Deep (WFD) and Deep Drilling Field (DDF) surveys within the Legacy Survey of Space and Time (LSS…
X-ray Studies of Planetary Systems: An Astro2010 Decadal Survey White Paper
Eric Feigelson, Jeremy Drake, Ronald Elsner +7
While it may seem counterintuitive that X-ray astronomy should give any insights into low-temperature planetary systems, planets orbit stars whose magnetized surfaces divert a smal…
Young stellar clusters and star formation throughout the Galaxy
Eric Feigelson, Fred Adams, Lori Allen +22
Most stars are born in rich young stellar clusters (YSCs) embedded in giant molecular clouds. The most massive stars live out their short lives there, profoundly influencing their…
Young Stars and their Variability with LSST
Rosaria Bonito, Patrick Hartigan, Laura Venuti +35
Young stars exhibit short-term photometric variability caused by mass accretion events from circumstellar disks, the presence of dusty warps within the inner disks, starspots that…
The APOGEE-2 Survey of the Orion Star Forming Complex: I. Target Selection and Validation with early observations
J'Neil Cottle, Kevin R. Covey, Genaro Suárez +26
The Orion Star Forming Complex (OSFC) is a central target for the APOGEE-2 Young Cluster Survey. Existing membership catalogs span limited portions of the OSFC, reflecting the diff…
The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
Kirpal Nandra, Didier Barret, Xavier Barcons +237
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of tw…
