Silicate Evolution in Brown Dwarf Disks
B. Riaz
We present a compositional analysis of the 10 micron silicate spectra for brown dwarf disks in the Taurus and Upper Scorpius (UppSco) star-forming regions, using archival Spitzer/I…
2MASS J17112318-2724315: A Deeply-Embedded Low-Mass Protostellar System in the B59 Molecular Cloud
B. Riaz, E. L. Martin, H. Bouy +1
We present near-infrared observations of the low-mass deeply-embedded Class 0/I system 2MASS J17112318-2724315 (2M171123) in the B59 molecular cloud. Bright scattered light nebulos…
First Confirmed Detection of a Bipolar Molecular Outflow from a Young Brown Dwarf
Ngoc Phan-Bao, Basmah Riaz, Chin-Fei Lee +6
Studying the earliest stages in the birth of stars is crucial for understanding how they form. Brown dwarfs with masses between that of stars and planets are not massive enough to…
New Brown Dwarf Disks in the TW Hydrae Association
B. Riaz, J. E. Gizis
In our analysis of {\it Spitzer}/IRS archival data on the stellar and sub-stellar members of the TW Hydrae Association (TWA), we have discovered two new brown dwarf disks: a flat o…
Spitzer Observations of Nearby M Dwarfs
Basmah Riaz, D. J. Mullan, John E. Gizis
We present Spitzer IRAC and MIPS observations for a sample of eight M dwarfs: six dMe, one dM, and one sdMe star. All of our targets are found to have SEDs which are fitted within…
Identification of New M Dwarfs in the Solar Neighborhood
Basmah Riaz, John E. Gizis, James Harvin
We present the results from a spectroscopic study of 1080 nearby active M dwarfs, selected by correlating the 2MASS and ROSAT catalogs. We have derived the spectral types and estim…
