A “Super-Jupiter” recently discovered by direct imaging techniques may not be as it initially seemed. Hinkley et al. find the system to be older than expected and the Super-Jupiter to really be a brown dwarf.
The mass of a substellar companion can help determine whether it’s a planet or a brown dwarf. But how can you measure the mass of a companion that you can’t detect directly? Look at the disk!
A new brown dwarf system has been discovered only 2 parsec away; Gillon et al. analyze its light curve to study clouds on the surfaces of these stars.
With the addition of these 87 new T dwarfs, WISE has now tripled the number of known T dwarfs with spectral type later than T5.
A wealth of observations tell an active accretion story within the Lambda Orionis Star Forming Region, at the head of the Orion constellation.
What happens to a low-mass companion when a star evolves off the main sequence to become a white dwarf?
The Wide-field Infrared Survey Explorer (WISE) data release promises many new and exciting discoveries!
This paper describes an incredibly variable brown dwarf. To fit this variability with models, a combination of thick clouds and clearer areas are needed. This means that there are big dusty storms that cover large fractions of 2M2139’s surface!
Today we will be discussing an exciting discovery – the first observations of an entirely new spectral class of stellar objects!
