A universal spin-mass relation for brown dwarfs and planets
Aleks Scholz, Keavin Moore, Ray Jayawardhana +3
While brown dwarfs show similarities with stars in their early life, their spin evolution is much more akin to that of planets. We have used lightcurves from the K2 mission to meas…
Discovery of a magnetic white dwarf with unusual short-period variability
Aleks Scholz, Joe Llama, Koraljka Muzic +3
We report the discovery of a magnetic white dwarf which shows periodic variability with P=110 min, color-dependent amplitudes and a transient phase shift in the blue compared to th…
M Stars in the TW Hya Association: Stellar X-rays and Disk Dissipation
Joel H. Kastner, David A. Principe, Kristina Punzi +4
To investigate the potential connection between the intense X-ray emission from young, low-mass stars and the lifetimes of their circumstellar, planet-forming disks, we have compil…
The Deepest Constraints on Radio and X-ray Magnetic Activity in Ultracool Dwarfs from WISE J104915.57-531906.1
R. A. Osten, C. Melis, B. Stelzer +5
We report upper limits to the radio and X-ray emission from the newly discovered ultracool dwarf binary WISE J104915.57531906.1 (Luhman 16AB). As the nearest ultracool dwarf bin…
Spectroscopy of Very Low Mass Stars and Brown Dwarfs in the Lambda Orionis Star Forming Region. I. Enlarging the census down to the planetary mass domain in Collinder 69
A. Bayo, D. Barrado, J. Stauffer +7
Whilst there is a generally accepted evolutionary scheme for the formation of low-mass stars, the analogous processes when moving down in mass to the brown dwarfs regime are not ye…
Emission Line Variability of the Accreting Young Brown Dwarf 2MASSW J1207334-393254: From Hours to Years
Beate Stelzer, Alexander Scholz, Ray Jayawardhana
We have obtained a series of high-resolution optical spectra for the brown dwarf 2MASSW J1207334-393254 (2M1207) using the ESO Very Large Telescope with the UVES spectrograph durin…
