Brown Dwarfs Stars Share Formation Process
2015/8/4
Astronomers using the Karl G. Jansky Very Large Array (VLA) have discovered jets of material ejected by still-forming young brown dwarfs. The discovery is the first direct evidence that brown dwarfs, ...
Study of Andromeda's stellar disk indicates more violent history than Milky Way（图）
Andromeda's stellar more violent history Milky Way
2015/1/20
A detailed study of the motions of different stellar populations in the disk of the Andromeda galaxy has found striking differences from our own Milky Way, suggesting a more violent history of mergers...
An optical study of the faint end of the stellar luminosity function
Stars Photometric functions Multicolor metering Height of fuzzy Projection Molecular cloud
2014/12/9
We implement a new method by which to study the faint end of the field star luminosity function. The method relies on deep, multicolor photometry of fields projected against highly obscured, nearby mo...
Multiwavelength study of parsec scale outflows associated with low mass young stellar objects
Arrow flow Low quality of the original star formation Optical observation star
2014/12/9
A multi-wavelength, multi-telescope observational study of recently discovered parsec-scale Herbig-Haro flows associated with the earliest stages of low mass protostellar formation is presented. Impro...
The Gas Properties of the W3 GMC: A HARP study
ISM Westerhout 3 submillimetre HARP study Gas Properties
2012/2/23
We present 12CO, 13CO and C18O J=3-2 maps of the W3 GMC made at the James Clerk Maxwell Telescope. We combine these observations with Five Colleges Radio Astronomy Observatory CO J=1-0 data to produce...
A Study of Gravitational Lens Chromaticity with the Hubble Space Telescope
A Study of Gravitational Lens Chromaticity with the Hubble Space Telescope
2011/10/20
We report Hubble Space Telescope observations of 6 gravitational lenses with the Advanced Camera for Surveys. We measured the flux ratios between the lensed images in 6 filters from 8140\AA\ to 2200\A...
The impact of quasars on their galaxy neighbors is an important factor in the understanding of the galaxy evolution models. The aim of this work is to characterize the close environments of quasars at...
An asteroseismic membership study of the red giants in three open clusters observed by Kepler: NGC6791, NGC6819, and NGC6811
asteroseismic membership study red giants clusters observed Kepler
2011/9/29
Studying star clusters offers significant advances in stellar astrophysics due to the combined power of having many stars with essentially the same distance, age, and initial composition. This makes c...
