Spectrophotometric properties of pre-main sequence stars: the Epsilon Chamaeleontis cluster
A-Ran Lyo, Warrick A. Lawson, M. S. Bessell
We present a study of flux-calibrated low-resolution optical spectroscopy of ten stars belonging to eight systems in the ~ 5 Myr-old Epsilon Chamaeleontis (Eps Cha) pre-main-sequen…
Doppler Images and Chromospheric Variability of TWA 6
M. B. Skelly, Y. C. Unruh, A. Collier Cameron +4
We present Doppler imaging and Balmer line analysis of the weak-line T Tauri star TWA 6. Using this data we have made one of the first attempts to measure differential rotation in…
The Stellar Population And Origin Of The Mysterious High-Latitude Star Forming Cloud CG 12
Konstantin Getman, Eric Feigelson, Warrick Lawson +2
The mysterious high galactic latitude cometary globule CG12 has been observed with the ACIS detector on board the Chandra X-ray Observatory. We detect 128 X-ray sources; half are l…
A deep photometric survey of the eta Chamaeleontis cluster down to the brown dwarf - planet boundary
A-Ran Lyo, Inseok Song, Warrick A. Lawson +2
We report the outcome of the deep optical/infrared photometric survey of the central region (33 X 33 arcmin or 0.9 pc^2) of the eta Chamaeleontis pre-main sequence star cluster. Th…
51 Eri and GJ 3305: A 10-15 Myr old binary star system at 30 parsecs
E. D. Feigelson, W. A. Lawson, M. Stark +5
Following the suggestion of Zuckerman et al. (2001, ApJ, 562, L87), we consider the evidence that 51 Eri (spectral type F0) and GJ 3305 (M0), historically classified as unrelated m…
Rotation periods for stars of the TW Hydrae association
Warrick A. Lawson, Lisa A. Crause
We have conducted a photometric study of late-type members of the TW Hydrae association (TWA) and measured the rotation periods for 16 stars in 12 systems. For TWA stars listed by…
