SLX 1746-331 is a galactic centre source and therefore suffer of large extinction. It showed outbursts in 2003 (Markwardt2003b), 2007 (Markwardt2007) and 2023 (Negoro2023a,Kennea2023). The peak X-ray flux is taken from the 2003 outburst. It also showed some activity in 2011 (Ozawa2011). The optical counterpart reported by Joshi2023 differs from the one reported during the 2017 outburst. Torres2023 re-analysed the IR data and found that the coordinates given in Torres2007b were erroneously reported, new coordinates are provided in Torres2023. The system showed another outburst in 2023 (Negoro2023a). The analysis of the X-ray flux and assuming an inclination of 0º was used by Peng2023 to estimate a lower limit to the mass of the compact object of 3&plumn;2 M☉ which would imply a BH accretion. |
