Using the Hubble Space Telescope, the 4 m Blanco Telescope at the Cerro Tololo Inter-American Observatory, and the Spitzer Space Telescope, we have performed deep imaging from 0.8 to 8 μm of the southern subcluster in the Chamaeleon I star-forming region. In these data, we have discovered an object, Cha 110913-773444, whose colors and magnitudes are indicative of a very low mass brown dwarf with a circumstellar disk. In a near-infrared spectrum of this source obtained with the Gemini Near…

A survey for planetary-mass brown dwarfs in the Chamaeleon I star-forming region
We have performed a search for planetary-mass brown dwarfs in the Chamaeleon I star-forming region using proper motions and photometry measured from optical and infrared images from the Spitzer Space
Young, Low-Mass Brown Dwarfs with Mid-Infrared Excesses
We have combined new I, J, H, and Ks imaging of portions of the Chamaeleon II, Lupus I, and Ophiuchus star-forming clouds with 3.6-24 ?m imaging from the Spitzer legacy program From Molecular Cores
Spectroscopy of Young Planetary Mass Candidates with Disks
It is now well established that many young brown dwarfs exhibit characteristics similar to classical T Tauri stars, including infrared excess from disks and emission lines related to accretion.
New Low-Mass Stars and Brown Dwarfs with Disks in the Chamaeleon I Star-Forming Region

A mid-infrared study of very low mass stars and brown dwarfs in Upper Scorpius
Context. To investigate the formation of sub-stellar objects, we observed a sample of ultracool dwarf members of the Upper Scorpius OB association. Aims. The properties of disks, such as their
Dusty Disks at the Bottom of the Initial Mass Function
Isolated planetary-mass objects (IPMOs) have masses close to or below the deuterium-burning mass limit (∼ )—at the bottom of the stellar initial mass function . We present an exploratory survey for


Using the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope, we have obtained mid-infrared photometry of the least massive known brown dwarf in the Chamaeleon I star-forming region. For
A Young Star near the Hydrogen-burning Limit
We show that V410 X-ray 3, toward the L1495E star-forming complex, is an object with a mass of 0.08-0.15 M☉ and an age of ~1 Myr. Nonetheless, it has emerged from its natal cloud and can be studied
