2003PASP..115....1V A Search for Core-Collapse Supernova Progenitors in Hubble Space Telescope Images SCHUYLER D. VAN DYK IPAC, California Institute of Technology, Mailcode 100-22, Pasadena, CA 91125; vandyk@ipac.caltech.edu AND WEIDONG LI AND ALEXEI V. FILIPPENKO Department of Astronomy, 601 Campbell Hall, University of California, Berkeley, CA 94720-3411; weidong@astro.berkeley.edu, alex@astro.berkeley.edu Received 2002 August 2; accepted 2002 October 14; published 2002 November 27 ABSTRACT. Identifying the massive progenitor stars that give rise to core-collapse supernovae (SNe) is one of the main pursuits of supernova and stellar evolution studies. Using ground-based images of recent, nearby SNe obtained primarily with the Katzman Automatic Imaging Telescope, astrometry from the Two Micron All Sky Survey, and archival images from the Hubble Space Telescope, we have attempted the direct identification of the progenitors of 16 Type II and Type Ib/c SNe. We may have identified the progenitors of the Type II SNe 1999br in NGC 4900, 1999ev in NGC 4274, and 2001du in NGC 1365 as supergiant stars with M_V_^0^ ~ -6 mag in all three cases. We may have also identified the progenitors of the Type Ib SNe 2001B in IC 391 and 2001is in NGC 1961 as very luminous supergiants with M_V_^0^ ~ -8 to -9 mag, and possibly the progenitor of the Type Ic SN 1999bu in NGC 3786 as a supergiant with M_V_^0^ ~ -7.5 mag. Additionally, we have recovered at late times SNe 1999dn in NGC 7714, 2000C in NGC 2415, and 2000ew in NGC 3810, although none of these had detectable progenitors on pre-supernova images. In fact, for the remaining SNe only limits can be placed on the absolute magnitude and color (when available) of the progenitor. The detected Type II progenitors and limits are consistent with red supergiants as progenitor stars, although possibly not as red as we had expected. Our results for the Type Ib/c SNe do not strongly constrain either Wolf-Rayet stars or massive interacting binary systems as progenitors. ======================================================================== 2003PASP..115...21V "A Search for Core-Collapse Supernova Progenitors in Hubble Space Telescope Images" (PASP, 115, 1 [2003]) SCHUYLER D.

FILIPPENKO Department of Astronomy, 601 Campbell Hall, University of California, Berkeley, CA 94720-3411; weidong@astro.berkeley.edu, alex@astro.berkeley.edu The multiband GO-9041 images of SN 2001du in NGC 1365, obtained by the Hubble Space Telescope on 2001 November 26 (see Fig. 24), have recently become publicly available and show the SN nearly coincident with the blue object B (see section 3.14 in our original paper). A detailed analysis of these images is in preparation. See journal.
