Observations of Ultracool dwarfs with ultracam on the vlt: a search for weather
We present multi-colour photometry of four field ultracool dwarfs with the triple-beam photometer ultracam. Data were obtained simultaneously in the Sloan-g band and a specially designed narrow-band NaI filter. The previously reported 1.8-hr period of Kelu-1 is here recovered in the g-band, but the lack of any significant variability in the NaI light of this object precludes any conclusion as t...
متن کاملObservations of Ultracool White Dwarfs
We present new spectroscopic and photometric measurements of the white dwarfs LHS 3250 and WD 0346]246. Along with F351[50, these white dwarfs are the coolest ones known, all with e†ective temperatures below 4000 K. Their membership in the Galactic halo population is discussed, and detailed comparisons of all three objects with new atmosphere models are presented. The new models consider the e†...
متن کاملMeeting the Cool Neighbours , VI : A search for nearby ultracool dwarfs in the Galactic Plane
Surveys for nearby low-luminosity dwarfs tend to avoid the crowded regions of the Galactic Plane. We have devised near-infrared colour-magnitude and colour-colour selection criteria designed to identify late-type M and early-type L dwarfs within 12 parsecs of the Sun. We use those criteria to search for candidates within the regions of the Galactic Plane (|b| < 10 o) covered by the Second Incre...
متن کاملCool 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...
متن کاملSpectroscopic distances of nearby ultracool dwarfs
We present updated results of spectroscopic follow-up observations of a sample of 45 M dwarf candidates identified by Phan-Bao et al. (2003) based on the DENIS photometry and proper motion measurements. Forty one of these are nearby late-M dwarfs (d<30 pc) with spectral types ranging from M5.0 to M8.5 computed from the spectral indices. One contaminant is probably an F-G main sequence star redd...
