Fossil Disk in the T Tauri Multiple System V 773 Tau
We present new multi-epoch near-infrared (NIR) and optical high-angular images of the V 773 Tau pre-main sequence triple system, a weak-line T Tauri (WTTS) system in which the presence of an evolved, " fossil " protoplanetary disk has been inferred on the basis of a significant infrared (IR) excess. Our images reveal a fourth object bound to the system, V 773 Tau D. While it is much fainter tha...
متن کاملCaptured at millimeter wavelengths: a flare from the classical T Tauri star DQ Tauri
For several hours on 2008 April 19, the T Tauri spectroscopic binary DQ Tau was observed to brighten, reaching a maximum detected flux of 468 mJy and likely making it (briefly) the brightest object at 3 mm in the Taurus star-forming region. We present the light curve of a rarely before observed millimeter flare originating in the region around a pre-main-sequence star, and the first from a clas...
متن کاملPeriodic variations in the colours of the classical T Tauri star RW Aur A
The classical T Tauri star RW Aur A is an irregular variable with a large amplitude in all photometric bands. In an extended series of photometric data we found small-amplitude periodic variations in the blue colours of the star, with a period of 2. 64. The period was relatively stable over several years. The amplitude of the periodic signal is 0. 21 in U–V, 0. 07 in B–V, and about 0. 02 in V–R...
متن کاملOptical Variability of the T Tauri Star Hh30
We report results of V RI photometric monitoring of the T Tauri star plus disk system HH30. We find that HH30 is highly variable over timescales of a few days with ∆V ∼ 1.5 mag, ∆I ∼ 1.1 mag. Furthermore we find hints of periodicity with periodograms indicating possible periods of 11.6 and 19.8 days. The V RI photometry is available through the anonymous ftp service. We model the variability wi...
متن کاملA Third Star in the T Tauri System.
New speckle holographic images of the T Tauri infrared companion (T Tauri IRC; T Tauri S) reveal it to be a double system with a sky-projected separation of 0&farcs;05, corresponding to a linear distance of 7 AU. The presence of this third star may account for the relative paucity of dust surrounding the IRC.
