System parameters of three short period cataclysmic variable stars
J. F. Wild, S. P. Littlefair, R. P. Ashley +9
Using photometric ULTRACAM observations of three new short period cataclysmic variables, we model the primary eclipse lightcurves to extract the orbital separation, masses, and rad…
HST spectra reveal accretion in MY Lupi
J. M. Alcala', C. F. Manara, K. France +5
The mass accretion rate is a crucial parameter for the study of the evolution of accretion discs around young low-mass stellar and substellar objects (YSOs). We revisit the case of…
PDS 144: The First Confirmed Herbig Ae - Herbig Ae Wide Binary
J. B. Hornbeck, C. A. Grady, M. D. Perrin +13
PDS 144 is a pair of Herbig Ae stars that are separated by 5.35" on the sky. It has previously been shown to have an A2Ve Herbig Ae star viewed at 83\circ inclination as its northe…
The unusual protoplanetary disk around the T Tauri star ET Cha
P. Woitke, B. Riaz, G. Duchene +15
We present new continuum and line observations, along with modelling, of the faint (6-8) Myr old T Tauri star ET Cha belonging to the eta Chamaeleontis cluster. We have acquired HE…
A Chandra X-ray detection of the L dwarf binary Kelu-1: Simultaneous Chandra and Very Large Array observations
M. Audard, R. A. Osten, A. Brown +4
Magnetic activity in ultracool dwarfs, as measured in X-rays and H, shows a steep decline after spectral type M7-M8. So far, no L dwarf has been detected in X-rays. In contrast,…
