The Brown Dwarf Kinematics Project (BDKP. III. Parallaxes for 70 Ultracool Dwarfs
- J. Faherty, A. Burgasser, +6 authors G. Anglada-Escud
- Physics
- 25 March 2012
We report parallax measurements for 70 ultracool dwarfs (UCDs) including 11 late-M, 32 L, and 27 T dwarfs. In this sample, 14 M and L dwarfs exhibit low surface gravity features, 6 are close binary… Expand
The Intrinsic Colors of RR Lyrae Variables: A Means to Determine Interstellar Reddening
- Katherine A. Guldenschuh, A. Layden, +10 authors A. Young
- Physics
- 17 June 2005
ABSTRACT We present refined BVI light curves for six field RR Lyrae variable stars. The refinements include new data and improved photometric calibration compared to our previous work. For each star,… Expand
Infrared aperture photometry at ESO (1983-1994) and its future use.
- N. V. D. Bliek, J. Manfroid, Patrice J. Bouchet
- Physics
- 1 November 1996
We describe the infrared (IR) photometric system for the single channel photometers at ESO, which have been used from 1983 until 1994. In addition to the broadband near infrared (NIR, 1 5 m)… Expand

On the difference between nuclear and contraction ages
- W. Lyra, A. Moitinho, N. V. D. Bliek, J. Alves
- Physics
- 1 March 2006
Context. Ages derived from low mass stars still contracting onto the main sequence often differ from ages derived from the high mass ones that have already evolved away from it. Aims. We investigate… Expand
HD 34700 is a T Tauri multiple system
- M. Sterzik, C. Melo, A. Tokovinin, N. V. D. Bliek
- Physics
- 1 May 2005
We have imaged the young double-lined spectroscopic binary HD 34700 in the near-infrared and find evidence for two faint, visual, stellar components at 5$\farcs$2 and 9$\farcs$2 distance.… Expand
High-Resolution Imaging at the SOAR Telescope
- A. Tokovinin, R. Cantarutti, +4 authors E. Mondaca
- Physics
- 20 October 2010
Bright single and binary stars were observed at the 4.1 m telescope with a fast electron-multiplication camera in the regime of partial turbulence correction by the visible-light adaptive optics… Expand
Evolution of young brown dwarf disks in the mid-infrared
- M. Sterzik, I. Pascucci, D. Apai, N. V. D. Bliek, C. Dullemond
- Physics
- 21 June 2004
We have imaged two bona-fide brown dwarfs with TReCS/GEMINI-S and find mid-infrared excess emission that can be explained by optically thick dust disk models. In the case of the young ( ≈ 2 Myr) Cha… Expand
SOAR Adaptive Module (SAM): Seeing Improvement with a UV Laser
- A. Tokovinin, R. Cantarutti, +4 authors N. V. D. Bliek
- Physics
- 19 August 2016
The adaptive module of the 4.1 m SOAR telescope, SOAR Adaptive Module (SAM), corrects ground-layer turbulence using an ultraviolet laser guide star. It has been commissioned in 2013 and it is in… Expand
Grain growth and dust settling in a brown dwarf disk - Gemini/T-ReCS observations of CFHT-BD-Tau 4
- D. Apai, I. Pascucci, +4 authors T. Henning
- Physics
- 14 September 2004
We present accurate mid-infrared observations of the disk around the young, bona fide brown dwarf CFHT-BD-Tau 4. We report GEMINI/T-ReCS measurements in the 7.9, 10.4 and 12.3 µm filters, from which… Expand
