Multiband (0.9-1.6 μm) images of the TW Hydrae association (TWA) brown dwarf 2MASSW J1207334-393254 (also known as 2M 1207) and its candidate planetary-mass companion (2M 1207b) were obtained on 2004 August 28 and 2005 April 26 with HST NICMOS. The images from these two epochs unequivocally confirm the two objects as a common proper motion pair (16.0 σ confidence). A new measurement of the proper motion of 2M 1207 implies a distance to the system of 59 ± 7 pc and a projected separation of 46…

2MASS J04435686+3723033 B: A Young Companion at the Substellar Boundary with Potential Membership in the β Pictoris Moving Group
We present a detailed characterization of 2MASS J04435750+3723031, a low-mass companion orbiting the young M2 star 2MASS J04435686+3723033 at 7.″6 (550 au) with potential membership in the 23 Myr β
The Planetary Mass Companion 2MASS 1207–3932B: Temperature, Mass, and Evidence for an Edge-on Disk
We present J-band imaging and H+K-band low-resolution spectroscopy of 2MASS 1207-3932AB, obtained with VLT NACO. For the putative planetary mass secondary, we find J = 20.0 ± 0.2 mag. The HK spectra
Identification of the TW Hya Association Member 2M1235 −39: a Tertiary Component of the HR 4796 System
Aims. We seek to determine whether the late-type star 2MASS J12354893−3950245 (2M1235−39) is a member of the TW Hya Association (TWA), a hypothesis suggested by its association with a bright X-ray

We imaged five objects near the star-forming clouds of Ophiuchus with the Keck Laser Guide Star AO system. We resolved sources 11 (Oph 16222-2405) and 16 (Oph 16233-2402) from Allers and coworkers
An accurate distance to 2M1207Ab
Context. In April 2004, the first image was obtained of a planetary mass companion (now known as 2M1207 b) in orbit around a self-luminous object different from our own Sun (the young brown dwarf
Characterizing the Disk around the TW Hydrae Association Brown Dwarf 2MASSW J1207334–393254
We present detailed modeling of the disk around the TW Hydrae Association (TWA) brown dwarf 2MASSW J1207334-393254 (2M1207), using Spitzer observations from 3.6 to 24 μm. The spectral energy

The highest resolution near infrared spectrum of the imaged planetary mass companion 2M1207 b
Direct-imaging searches for planets reveal wide orbit planets amenable to spectroscopy, and their atmospheres represent an important comparison to the irradiated atmospheres of Hot Jupiters. Using AO
