J/A+A/418/869       M31-RV evolution (1942-1993)             (Boschi+, 2004)

M31-RV evolution and its alleged multi-outburst pattern. Boschi F., Munari U. <Astron. Astrophys. 418, 869 (2004)> =2004A&A...418..869B
ADC_Keywords: Novae ; Observatory log Keywords: stars: AGB and post-AGB - stars: novae, cataclysmic variables - stars: peculiar - stars: individual: V838 Mon - stars: individual: M31-RV - galaxies: individual: M31 Description: The photometric evolution of M31-RV has been investigated on 1447 plates of the Andromeda galaxy obtained over half a century with the Asiago telescopes. M31-RV is a gigantic stellar explosion that occurred during 1988 in the Bulge of M31 and that was characterized by the appearance for a few months of an M supergiant reaching Mbol=-10. The 1988 outburst has been positively detected on Asiago plates, and it has been the only such event recorded over the period covered by the plates (1942-1993). In particular, an alleged previous outburst in 1967 is excluded by the more numerous and deeper Asiago plates, with relevant implication for the interpretative models of this unique event.

Note (7): A null value indicates that we were unable to estimate a limiting magnitude around M31-RV for a number of reasons, including bad focusing, a too low S/N, or a position of M31-RV too close to the plate border for the comparison sequence to be entirely present on the plate.
