Photometric Variability of the T2.5 Brown Dwarf Simp J013656.5+093347; Evidence for Evolving Weather Patterns
We report the discovery of a photometric variability in the bright T2.5 brown dwarf SIMP J013656.57+093347.3. Continuous J-band photometry has been obtained for several hours on four different nights. The light curves show a periodic modulation with a period of ∼2.4 hours, a peak-to-peak amplitude of ∼ 50 mmag and significant night-to-night evolution. We suggest that the light curve modulation ...
متن کاملPeriodic photometric variability of the brown dwarf Kelu - 1
We have detected a strong periodicity of 1.80±0.05 hours in photometric observations of the brown dwarf Kelu-1. The peak-to-peak amplitude of the variation is ∼1.1% (11.9±0.8 mmag) in a 41nm wide filter centred on 857nm and including the dust/temperature sensitive TiO & CrH bands. We have identified two plausible causes of variability: surface features rotating into-and out-of-view and so modul...
متن کاملThe Magnetosphere of the Ultracool Dwarf
Ultracool dwarfs, the least-massive contributors to the stellar mass function, exhibit striking magnetic properties that are inconsistent with trends for more massive stars. Here, we present the widestband radio observations to date of an ultracool dwarf, DENIS-P J104814.9−395604, in four 2GHz bandwidths between wavelengths of 1 cm and 10 cm. These data were obtained with the Australia Telescop...
متن کاملA comparison of chemistry and dust cloud formation in ultracool dwarf model atmospheres
The atmospheres of substellar objects contain clouds of oxides, iron, silicates, and other refractory condensates. Water clouds are expected in the coolest objects. The opacity of these ‘dust’ clouds strongly affects both the atmospheric temperature-pressure profile and the emergent flux. Thus any attempt to model the spectra of these atmospheres must incorporate a cloud model. However the dive...
متن کاملPhotometric variability of a young, low-mass brown dwarf
We report differential I-band and J-band photometry of S Ori 45, a cool (spectral type M8.5), young (1–8 Myr) brown dwarf of the σOrionis cluster with a likely mass estimated at around 20 times the mass of Jupiter. We detect variability (amplitudes ranging from 34 to 81 mmag) and observe a modulation at a period of 2.5–3.6 h in both optical and near-infrared light curves. The most recent optica...
