Photometric Observations of the 2017 Outburst of Recurrent Nova M31N 2007-10b

TL;DR

This paper presents photometric observations confirming that the 2017 outburst of M31N 2017-12a is a recurrence of the 2007-10b nova, contributing to the understanding of recurrent novae in M31.

Contribution

It provides the first confirmed photometric evidence linking the 2017 outburst to the 2007-10b nova in M31, enhancing knowledge of recurrent nova behavior.

Findings

Confirmed the 2017 outburst as a recurrence of M31N 2007-10b.

Provided detailed photometric data of the 2017 outburst.

Supported the classification of M31N 2017-12a as a recurrent nova.

Abstract

M31 is an ideal laboratory for observing and studying recurrent novae. To date, there have been 18 recurrent nova discovered in M31, six of which have recurrence periods less than nine years. M31N 2017-12a (AT2017jdm) is a transient that was reported near the center of M31, with the time of outburst estimated to be 2017 December 24.141 +/- 0.42 based on constraints from previous data. Here we present the photometric observations of M31N 2017-12a, which we confirm as a recurrence of M31N 2007-10b.
