The First Extensive Spectroscopic Study of Young Stars in the North America and Pelican Nebulae Region
Min Fang, Lynne A. Hillenbrand, Jinyoung Serena Kim +5
We present a spectroscopic survey of over 3400 potential members in the North America and Pelican nebulae (NAP) using several low-resolution ( 1300-2000) spectrographs: P…
An Overview of the LSST Image Processing Pipelines
James Bosch, Yusra AlSayyad, Robert Armstrong +31
The Large Synoptic Survey Telescope (LSST) is an ambitious astronomical survey with a similarly ambitious Data Management component. Data Management for LSST includes processing on…
Gaia Data Release 2. Summary of the contents and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
Gaia Data Release 2. Short-timescale variability processing and analysis
M. Roelens, L. Eyer, N. Mowlavi +13
The Gaia DR2 sample of short-timescale variable candidates results from the investigation of the first 22 months of Gaia photometry for a subsample of sources at the Gaia faint end…
Gaia Data Release 2: Observations of solar system objects
Gaia Collaboration, F. Spoto, P. Tanga +4
The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Gaia Data Release 2 (DR2…
Gaia Data Release 2: Properties and validation of the radial velocities
D. Katz, P. Sartoretti, M. Cropper +51
For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…
