The 2010 Eruption of the Recurrent Nova U Scorpii: The Multi-Wavelength Light Curve
Ashley Pagnotta, Bradley E. Schaefer, James L. Clem +8
The recurrent nova U Scorpii most recently erupted in 2010. Our collaboration observed the eruption in bands ranging from the Swift XRT and UVOT w2 (193 nm) to K-band (2200 nm), wi…
The RR Lyrae variables and Horizontal Branch of NGC6656 (M22)
Andrea Kunder, Peter B. Stetson, Santi Cassisi +10
The first calibrated broadband UBVI time-series photometry is presented for the RR Lyrae variable stars in NGC6656 (M22), with observations spanning a range of twenty-two years. We…
The effects of differential reddening and stellar rotation on the appearance of multiple populations in star clusters: the case of Trumpler 20
I. Platais, C. Melo, S. N. Quinn +6
We present a detailed analysis of the upper main sequence of the 1.3 Gyr old open cluster Trumpler 20. High accuracy BV photometry combined with the Very Large Telescope/FLAMES med…
Deep, Wide-field CCD Photometry for the Open Cluster NGC3532
James L. Clem, Arlo U. Landolt, D. W. Hoard +1
We present the results of a deep, wide-field CCD survey for the open cluster NGC~3532. Our new photometry effectively covers a one square degree area and reaches an un…
Bright Variable Stars in NGC 6819 - An Open Cluster in the Kepler Field
Antonio Talamantes, Eric L. Sandquist, James L. Clem +3
We describe a variability study of the moderately old open cluster NGC 6819. We have detected 4 new detached eclipsing binaries near the cluster turnoff (one of which may be in a t…
SN 2007od: A Type IIP SN with Circumstellar Interaction
J. E. Andrews, J. S. Gallagher, Geoffrey C. Clayton +9
SN 2007od exhibits characteristics that have rarely been seen in a Type IIP supernova (SN). Optical V band photometry reveals a very steep brightness decline between the plateau an…
