Measuring Magnetic Fields in Ultracool Stars and Brown Dwarfs

We present a new method for direct measurement of magnetic fields on ultracool stars and brown dwarfs. It takes advantage of the Wing-Ford band of FeH, which are seen throughout the M and L spectral types. These molecular features are not as blended as other optical molecular bands, are reasonably strong through most of the spectral range, and exhibit a response to magnetic fields which is easi...

Brown Dwarfs and Cool Stars

We review the current picture of disks around cool stars and brown dwarfs, including disk fractions, mass estimates, disk structure and dispersal, accretion, dust composition, the debris disk phase. We discuss these in the framework of recent planet formation models. The study of disks around brown dwarfs and cool stars allows testing disk physics and planet formation processes in a parameter r...

Young stars and brown dwarfs surrounding

Aims. We look for new regions for the search of substellar objects. Methods. Two circular areas, 45 arcmin-radius each, centred on the young massive star systems Alnilam and Mintaka in the Orion Belt, have been explored. The regions are very young (less than 10 Ma), have low extinction, and are neighbours to σ Orionis (∼3 Ma), a young open cluster very rich in brown dwarfs and planetary-mass ob...

Cool versus Ultracool White Dwarfs

A preliminary BV RIJHK analysis of the white dwarfs SSSPM J2231−7514 and SSSPM J2231−7515 is presented. Although both stars were reported to have Teff < 4000 K, the analysis here indicates Teff ≈ 4250 K for both SSSPM J2231−7514 and SSSPM J2231−7515. Given substantial scientific interest in the coolest extant degenerate stars, it is necessary to distinguish sub 4000 K objects from the bulk of c...

Very Low Mass Stars and Brown Dwarfs in Taurus-Auriga

We present high resolution optical spectra obtained with the HIRES spectrograph on the W. M. Keck I telescope of seven low mass T Tauri stars and brown dwarfs (LMTTs) in Taurus-Auriga. The observed Li I 6708 Å absorption, low surface gravity signatures, and radial velocities confirm that all are members of the Taurus star forming region; no new spectroscopic binaries are identified. Four of the...
