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…
An IPHAS-based search for accreting very low-mass objects using VO tools
L. Valdivielso, E. L. Martin, H. Bouy +6
The main goal of this paper is to prove that accreting very low-mass stars and brown dwarfs can be identified in IPHAS, a Halpha emission survey of the northern Milky Way.Full expl…
Optical variability of the ultracool dwarf TVLM 513-46546: evidence for inhomogeneous dust clouds
S. P. Littlefair, V. S. Dhillon, T. R. Marsh +3
We present multi-colour photometry of the M8.5V ultracool dwarf "pulsar" TVLM 513-46546 (hereafter TVLM 513) obtained with the triple-beam photometer ULTRACAM. Data were obtained s…
Low-resolution spectroscopy and spectral energy distributions of selected sources towards sigma Orionis
J. A. Caballero, L. Valdivielso, E. L. Martin +3
Aims: We investigated in detail nine sources in the direction of the young sigma Orionis cluster, which is considered a unique site for studying stellar and substellar formation. T…
A deep look into the cores of young clusters I. sigma-Orionis
H. Bouy, N. Huelamo, E. L. Martin +9
Nearby young clusters are privileged places to study the star formation history. Over the last decade, the sigma-Orionis cluster has been a prime location for the study of young ve…
Ground-based Optical and SPITZER Infrared Imaging Observations of Comet 21P/Giacobini-Zinner
Jana Pittichova, Charles E. Woodward, Michael S. Kelley +1
We present ground-based optical and Spitzer Space Telescope infrared imaging observations of the ecliptic (Jupiter-family) comet 21P/Giacobini-Zinner, the parent body of the Dracon…
