The First Hypervelocity Star from the Lamost Survey
We report the first hypervelocity star (HVS) discovered from the LAMOST spectroscopic survey. It is a B-type star with a heliocentric radial velocity about 620 km s, which projects to a Galactocentric radial velocity component of ∼477 km s. With a heliocentric distance of ∼13 kpc and an apparent magnitude of ∼13 mag, it is the nearest bright HVS currently known. With a mass of ∼9M⊙, it is one o...
متن کاملA Catalog of Moving Group Candidates in The Solar Neighborhood
Based on kernel estimator and wavelet technique, we have identified 22 moving group candidates in the solar neighborhood from a sample which includes around 14000 dwarfs and 6000 giants. Six of them were previously known as the Hercules stream, the Sirus-UMa stream, the Hyades stream, the Caster group, the Pleiades stream and the IC 2391; five of them have also been reported by other authors. E...
متن کاملA Catalog of Msx Infrared Dark Cloud Candidates
We use 8.3μm mid-infrared images acquired with the Midcourse Space Experiment satellite to identify and catalog Infrared Dark Clouds (IRDCs) in the first and fourth quadrants of the Galactic plane. Because IRDCs are seen as dark extinction features against the diffuse Galactic infrared background, we identify them by first determining a model background from the 8.3 μm images and then searching...
متن کاملA Catalog of Kepler Habitable Zone Exoplanet Candidates
The NASA Kepler mission ha s discovered thousands of new planetary candidates, many of which have been confirmed through follow-up observations. A primary goal of the mission is to determine the occurrence rate of terrestrial-size planets within the Habitable Zone (HZ) of their host stars. Here we provide a list of HZ exoplanet candidates from the Kepler Q1–Q17 Data Release 24 data-vetting proc...
متن کاملDissolving star cluster candidates
We present a list of 34 neglected entries from star cluster catalogues located at relatively high galactic latitudes (|b| > 15) which appear to be candidate late stages of star cluster dynamical evolution. Although underpopulated with respect to usual open clusters, they still present a high number density contrast as compared to the galactic field. This was verified by means of (i) predicted m...
