SPITZER OBSERVATIONS OF THE λ ORIONIS CLUSTER. II. DISKS AROUND SOLAR-TYPE AND LOW-MASS STARS
solar-type the low-mass stellar population
2014/12/22
We present IRAC/MIPS Spitzer Space Telescope observations of the solar-type and the low-mass stellar population of the young (~5 Myr) λ Orionis cluster. Combining optical and Two Micron All Sky Survey...
The spatial distribution of star formation in the solar neighbourhood: do all stars form in dense clusters?
low-mass neighbours Spitzer Space Telescope
2014/12/20
We present a global study of low-mass, young stellar object (YSO) surface densities (ヒ) in nearby (<500 >pc) star-forming regions based on a comprehensive collection of Spitzer Space Telescope surveys...

Solar modulation during the Holocene
Solar modulation Holocene cosmogenic radionuclides neutron monitor
2009/5/27
We built a composite of three reconstructions of the solar modulation function over the Holocene. The reconstructions until 1950 are based on data from cosmogenic radionuclides and the present time (1...
16 December, 2006，The surprises began early on, with the second grain Brownlee worked on in his laboratory -- a calcium-aluminum inclusion, a rare material found in some meteorites. The stunning thing...
