The Massive Progenitor of the Type II-Linear SN 2009kr

N. Elias-Rosa, S. D. Van Dyk, W. Li +13

We present early-time photometric and spectroscopic observations of supernova (SN) 2009kr in NGC 1832. We find that its properties to date support its classification as Type II-lin…

Pre-main sequence stars in the Cepheus flare region

M. Kun, Z. Balog, S. J. Kenyon +2

We present results of optical spectroscopic and BVR_CI_C photometric observations of 77 pre-main sequence (PMS) stars in the Cepheus flare region. A total of 64 of these are newly…

Mass Outflow from Red Giant Stars in M13, M15, and M92

Sz. Mészáros, E. H. Avrett, A. K. Dupree

Chromospheric model calculations of the Halpha line for selected red giant branch (RGB) and asymptotic giant branch (AGB) stars in the globular clusters M13, M15, and M92 are const…

SPITZER/IRAC-MIPS Survey of NGC2451A and B: Debris Disks at 50-80 million years

Zoltan Balog, Laszlo L. Kiss, Jozsef Vinko +5

We present a Spitzer IRAC and MIPS survey of NGC 2451 A and B, two open clusters in the 50-80 Myr age range. We complement these data with extensive ground-based photometry and spe…

Mass Outflow and Chromospheric Activity of Red Giant Stars in Globular Clusters II. M13 and M92

Sz. Mészáros, A. K. Dupree, T. Szalai

High resolution spectra of 123 red giant stars in the globular cluster M13 and 64 red giant stars in M92 were obtained with Hectochelle at the MMT telescope. Emission and line asym…
