Light Echoes of Ancient Transients with the Blanco CTIO 4m Telescope
A. Rest, B. Sinnott, D. L. Welch +5
For over a century, light echoes have been observed around variable stars and transients. The discovery of centuries-old light echoes from supernovae in the Large Magellanic Cloud…
Variable Stars in Metal-Rich Globular Clusters. IV. Long Period Variables in NGC 6496
Mohamad Abbas, Andrew Layden, Katherine Guldenschuh +6
We present VI-band photometry for stars in the metal-rich globular cluster NGC 6496. Our time-series data were cadenced to search for long period variables (LPVs) over a span of ne…
Light echoes reveal an unexpectedly cool Eta Carinae during its 19th-century Great Eruption
A. Rest, J. L. Prieto, N. R. Walborn +14
Eta Carinae (Eta Car) is one of the most massive binary stars in the Milky Way. It became the second-brightest star in the sky during its mid-19th century "Great Eruption," but the…
The effects of dust on the optical and infrared evolution of SN 2004et
J. Fabbri, M. Otsuka, M. J. Barlow +8
We present an analysis of multi-epoch observations of the Type II-P supernova SN 2004et. New and archival optical spectra of SN 2004et are used to study the evolution of the Halpha…
The destruction and survival of dust in the shell around SN 2008S
R. Wesson, M. J. Barlow, B. Ercolano +8
SN 2008S erupted in early 2008 in the grand design spiral galaxy NGC 6946. The progenitor was detected by Prieto et al. in Spitzer Space Telescope images taken over the four years…
The MACHO Project HST Follow-Up: The Large Magellanic Cloud Microlensing Source Stars
C. A. Nelson, A. J. Drake, K. H. Cook +21
We present Hubble Space Telescope (HST) WFPC2 photometry of 13 microlensed source stars from the 5.7 year Large Magellanic Cloud (LMC) survey conducted by the MACHO Project. The mi…
