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…
HST search for M subdwarf binaries
Basmah Riaz, John E. Gizis, Debasmita Samaddar
We present HST/ACS observations of 19 nearby M subdwarfs in a search for binary systems. Other than the wide common proper motion pair LHS 2140/2139, none of our sdM and esdM targe…
Characterizing the disk around the TW Hydrae Association brown dwarf 2MASSW J1207334-393254
Basmah Riaz, John E. Gizis
We present detailed modeling of the disk around the TW Hydrae Association (TWA) brown dwarf 2MASSW J1207334-393254 (2M1207), using {\it Spitzer} observations from 3.6 to 24 $\micro…
Infrared observations of a mid-L dwarf with strong H emission
Basmah Riaz, John E. Gizis
We present {\it Spitzer}/IRAC observations of the L5 dwarf, 2MASSI J1315309-264951 (2M1315). This ultracool dwarf is known to display strong emission in the H line. The SED for…
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…
