A mini - survey for variability in early L dwarfs [
نویسندگان
چکیده
We report differential I-band photometry of four early L-dwarfs obtained to study variability. We detect variability on the timescale of hours in two objects, 2M0746425+200032 (at a level of 0.007 mag – 6.5 sigma) and 2M1108307+683017 (0.012 mag – 5 sigma). We also place upper limits of 0.02 mag (1 sigma) on the variability of two others.

Optical spectroscopy of DENIS mini-survey brown dwarf candidates
We present optical (6500-9200Å) spectroscopy of eight cool dwarfs detected in a 231 square degree “Mini-survey” of the Deep NEar Infrared Survey (DENIS) data. We are able to confirm that the spectral types derived from the Mini-survey infrared spectroscopy are meaningful. We provide a spectral sequence which extends beyond the M-dwarf range and into the proposed “L” class of dwarfs. The dominan...
متن کاملPeriodic Optical Variability of Radio Detected Ultracool Dwarfs
A fraction of very low mass stars and brown dwarfs are known to be radio active, in some cases producing periodic pulses. Extensive studies of two such objects have also revealed optical periodic variability and the nature of this variability remains unclear. Here we report on multi-epoch optical photometric monitoring of six radio detected dwarfs, spanning the ∼M8 L3.5 spectral range, conducte...
متن کاملA mini-survey of ultracool dwarfs at 4.9 GHz
Context. A selection of ultracool dwarfs are known to be radio active, with both gyrosynchrotron emission and the electron cyclotron maser instability being given as likely emission mechanisms. Aims. We explore whether ultracool dwarfs previously undetected at 8.5 GHz may be detectable at a lower frequency. Methods. We select a sample of fast rotating ultracool dwarfs with no detectable radio a...
متن کاملChromospheric Activity, Rotation, and Rotational Braking in M and L Dwarfs
We present results from a high-resolution spectroscopic survey of 45 L dwarfs, which includes both very low-mass stars and brown dwarfs. Our spectra allow us to derive a significant number of new rotational velocities, and discover a slowly rotating (in projected velocity) L dwarf that allows more accurate measurement of spectroscopic rotations for these objects. We measure chromospheric activi...
متن کاملVolume-limited radio survey of ultracool dwarfs
Aims. We aim to increase the sample of ultracool dwarfs studied in the radio domain to allow a more statistically significant understanding of the physical conditions associated with these magnetically active objects. Methods. We conducted a volume-limited survey at 4.9 GHz of 32 nearby ultracool dwarfs with spectral types covering the range M7 – T8. A statistical analysis was performed on the ...
