Results of the ROTOR-program. I. The long-term photometric variability of classical T Tauri stars
K. N. Grankin, S. Yu. Melnikov, J. Bouvier +2
We present a unique, homogeneous database of photometric measurements for Classical T Tauri stars extending up to 20 years. The database contains more than 21,000 UBVR observations…
Testing the Disk-Locking Paradigm: An Association Between U-V Excess and Rotation in NGC 2264
Cassandra Fallscheer, William Herbst
We present some results from a UVI photometric study of a field in the young open cluster NGC 2264 aimed, in part, at testing whether accretion in pre-main sequence stars is linked…
The Recurrent Eclipse of an Unusual Pre--Main-Sequence Star in IC 348
S. Nordhagen, W. Herbst, E. C. Williams +1
The recurrence of a previously documented eclipse of a solar-like pre--main-sequence star in the young cluster IC 348 has been observed. The recurrence interval is 4.7 yr…
The Variability and Rotation of Pre-main Sequence Stars in IC 348: Does Intracluster Environment Influence Stellar Rotation?
S. Nordhagen, W. Herbst, K. L. Rhode +1
A variability study of the young cluster IC 348 at Van Vleck Observatory has been extended to a total of seven years. Twelve new periodic stars have been found in the last two year…
Evidence for Differential Rotation on a T Tauri Star
W. Herbst, S. Dhital, A. Francis +3
Five years of photometric monitoring of the T Tauri star HBC 338 in NGC 1333 has revealed that it is a periodic variable, but the period has changed significantly with time. From 2…
The Rotation of Young Low-Mass Stars and Brown Dwarfs
W. Herbst, J. Eisloeffel, R. Mundt +1
We review the current state of our knowledge concerning the rotation and angular momentum evolution of young stellar objects and brown dwarfs from a primarily observational view po…
