First Detection of a Strong Magnetic Field on a Bursty Brown Dwarf: Puzzle Solved
S. V. Berdyugina, D. M. Harrington, O. Kuzmychov +4
We report the first direct detection of a strong, 5 kG magnetic field on the surface of an active brown dwarf. LSR J1835+3259 is an M8.5 dwarf exhibiting transient radio and optica…
First spectropolarimetric measurement of a brown dwarf magnetic field in molecular bands
Oleksii Kuzmychov, Svetlana V. Berdyugina, David M. Harrington
We present the first measurement of the surface magnetic field of a late-M dwarf, LSR J1835+3259, with the help of the full-Stokes spectropolarimetry in the bands of diatomic molec…
Correcting systematic polarization effects in Keck LRISp spectropolarimetry to <0.05%
David M. Harrington, Svetlana V. Berdyugina, Oleksii Kuzmychov +1
Spectropolarimetric measurements at moderate spectral resolutions are effective tracers of stellar magnetic fields and circumstellar environments when signal to noise ratios (SNRs)…
Magnetic field on the brown dwarf LSR J1835+3259
O. Kuzmychov, S. Berdyugina, D. Harrington
We model the full-Stokes spectrum of the brown dwarf LSR J1835+3259 in the bands of the diatomic molecules CrH, TiO, and FeH in order to infer its magnetic properties. The models a…
Paschen-Back effect in the CrH molecule and its application for magnetic field measurements on stars, brown dwarfs, and hot exoplanets
O. Kuzmychov, S. Berdyugina
We investigated the Paschen-Back effect in the (0,0) band of the A6Σ+-X6Σ+ system of the CrH molecule, and we examined its potential for estimating magnetic fields on stars and sub…
Investigating the magnetism of brown dwarfs
O. Kuzmychov, S. Berdyugina, D. Harrington +1
We model the spectra of two brown dwarfs observed with the low resolution spectropolarimeter LRIS (Keck observatory) during several rotational phases in order to infer their magnet…
