NAOC, CAS; 2 Physics Depart. Tsinghua U.; 3. Depart. of Astronomy, UC Berkeley; 4. Depart. of Astronomy, Beijing Normal U. | | Abstract: | The progenitor of type II-plateau supernova (SN) 2004dj is identified with a supergiant in a compact star cluster known as "Sandage Star 96" (S96) in the nearby spiral galaxy NGC 2403, which was fortuitously imaged as part of the Beijing-Arizona-Taiwan-Connecticut (BATC) Multicolor Sky Survey from Feb 1995 to Dec 2003 prior to SN 2004dj. The superior photometry of BATC images for S96, taken with 14 intermediate-band filters covering 3000-10000AA, unambiguously establishes the star cluster nature of S96 with an age of $sim 20$Myr, a reddening of $hbox{E}(B-V)sim 0.35$ mag and a total mass of $sim 96,000$M$_{odot}$. The compact star cluster nature of S96 is also consistent with the lack of light variations in the past decade. The SN progenitor is estimated to have a main-sequence mass of $sim$12M$_{odot}$. The comparison of our intermediate-band data of S96 with the post-outburst photometry obtained as the SN has significantly dimmed, may hopefully conclusively establish the nature of the progenitor. | | Source: | arXiv, astro-ph/0505305 | | Services: | Forum | Review | PDF | Favorites | |
