Title: | Optical identification of the supersoft X-ray source 1E0035.4-7230 in the Small Magellanic Cloud | Authors: | ORIO, Marina DELLA VALLE, Massimo MASSONE, Giuseppe Ogelman, H. |
Issue Date: | 1994 | Journal: | ASTRONOMY & ASTROPHYSICS | Number: | 289 | First Page: | L11 | Abstract: | We report the identification of the optical counter-part of the SMC super-soft X-ray source 1E0035.4-7230 with a variable star of magnitude B=19.9-20.2 within the 40" Einstein error box. The star shows strong UV excess, a hot, blue continuum and weak lines of high ionization. The lines are redshifted by 3-4A, indicating SMC membership. This object appears similar to CAL 83 and CAL 87 and is probably a binary system hosting an accreting, hydrogen burning white dwarf. | URI: | http://hdl.handle.net/20.500.12386/32671 | URL: | https://ui.adsabs.harvard.edu/abs/1994A%26A...289L..11O/abstract | ISSN: | 0004-6361 | Bibcode ADS: | 1994A&A...289L..11O | Fulltext: | open |
