Rotation periods of the Hyades open cluster using ASAS light curves : measuring the Hyades gyro-age and benchmarking tools for gyrochronology studies with LSST
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)
Rotation period distributions for older open clusters are difficult to obtain because of the general scarcity of clusters with ages greater than 200 Myr, as well as the challenge of measuring rotation periods for less ...
Structure function analysis of blazars AP Librae and 3c279
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-27)
Blazars AP Librae and 3c279 are analyzed for microvariability using a technique known as structure function analysis. AP Librae was observed in April of 2005 and 3c279 was observed in April of 2007. The data for AP Librae ...
A Search for Pre-Main Sequence Eclipsing Binary Stars in the Lagoon Nebula
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
We report time-series CCD I-band photometry for the pre-main-sequence cluster NGC 6530, located within the Lagoon Nebula. The data were obtained with the 4Kx4K imager on the SMARTS 1.0m telescope at CTIO on 36 nights over ...
