ATel #12237: A B1-2e optical classification for the optical counterpart of XTE J0052-723 (SXP 4.78; Swift J005139.2-721704)

Building upon our previous ATel #12224 we managed to obtain an optical spectrum of the counterpart. The full text follows: ATel #12237; G. Maravelias (NOA), V. Antoniou (TTU/SAO), K. Boutsia (LCO), A. Zezas (UoC/SAO), A. Z. Bonanos (NOA), F. Haberl (MPE), D. Hatzidimitriou (UoA/NOA) on 21 Nov 2018; 23:36 UT / In ATel #12224 we […]

New paper: Exploring the circumstellar disk-like structure of the B[e] supergiant LHA 120-S 73

Finally after almost a year, our proceedings paper on the B[e] supergiant LHA 120-S 73 is out! It is based on a poster (2015-58aaa-torres-s73) presented on the 58th Annual Meeting of the Argentinian Astronomical Society (La Plata, Argentina, Sep 14-18, 2015) and connected also with our last refereed paper. Exploring the circumstellar disk-like structure of […]
