Multiwaveband photometry of the irradiated brown dwarf WD0137−349B
WD0137−349 is a white dwarf–brown dwarf binary system in a 116 min orbit. We present radial velocity observations and multiwaveband photometry from V, R and I in the optical, to J, H and Ks in the near-IR and [3.6], [4.5], [5.8] and [8.0] μm in the mid-IR. The photometry and light curves show variability in all wavebands, with the amplitude peaking at [4.5] μm, where the system is also brightes...
متن کاملExploring Brown Dwarf Disks
We discuss the spectral energy distribution of three very low mass objects in Chamaeleon I for which ground-based spectroscopy and photometry as well as ISO measurements in the mid-infrared are available (Comerón et al. 2000; Persi et al. 2000). One of these stars (Cha Hα1) is a bona-fide brown dwarf, with mass 0.04–0.05 M⊙. We show that the observed emission is very well described by models of...
متن کاملBrown Dwarf Disks With
We present ALMA continuum and spectral line data at 0.89 mm and 3.2 mm for three disks surrounding young brown dwarfs and very low mass stars in the Taurus star forming region. Dust thermal emission is detected and spatially resolved for all the three disks, while CO(J = 3 − 2) emission is seen in two disks. We analyze the continuum visibilities and constrain the disks physical structure in dus...

متن کاملSecondary Eclipse Observations of the Highly Irradiated Transiting Brown Dwarf Kelt-1b
We present secondary eclipse observations of the highly irradiated transiting brown dwarf KELT-1b. These observations represent the first constraints on the atmospheric dynamics of a highly irradiated brown dwarf, the atmospheres of irradiated giant planets at high surface gravity, and the atmospheres of brown dwarfs that are dominated by external, rather than internal, energy. Using the Spitze...
