Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

Stable, hydrogen-burning, M dwarf stars make up about 75% of all stars in the Galaxy. They
are extremely long-lived, and because they are much smaller in mass than the Sun …

ABSTRACT The c2d Spitzer Legacy project obtained images and photometry with both
IRAC and MIPS instruments for five large, nearby molecular clouds. Three of the clouds …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

Dust is a ubiquitous feature of the cosmos, im**ing directly or indirectly on most fields of
modern astronomy and astrophysics. Dust in the Galactic Environment, Second Edition …

We use a semianalytic circumstellar disk model that considers movement of the snow line
through evolution of accretion and the central star to investigate how gas giant frequency …

Abstract We report new Spitzer Space Telescope observations, using the IRAC and MIPS
instruments, of the young (~ 3 Myr) σ Orionis cluster. We identify 336 stars as members of the …

We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0,
and 24 μm that were obtained during the cryogenic mission of the Spitzer Space Telescope …

I have used high-precision photometry and astrometry from the third data release of Gaia to
perform a survey for members of the Taurus star-forming region and young associations in …

We report 24 and/or 70 μm measurements of~ 160 A-type main-sequence stars using the
Multiband Imaging Photometer for Spitzer (MIPS). Their ages range from 5 to 850 Myr …
