Notes on the density of the disk/rings around B[e] supergiants

In Zickgraf et al. 1989 (A&A, 220, 206) there is a comment on the density of the disk around the supergiant LHA 115-S 18. In Table 1 they provide (following Waters 1986) the mean particle density at r=R* for a number of sources: 3.2 x 1012, 2.6 x 1012, 4.6 x 1012, 1.7 x 1012 […]

New Paper on BeXRBs – 5 new BeXRBs in the SMC and the link of the supergiant B[e] star LHA 115-S 18 with an X-ray source

Optical spectra of 5 new Be/X-ray Binaries in the Small Magellanic Cloud and the link of the supergiant B[e] star LHA 115-S 18 with an X-ray source Grigoris Maravelias, Andreas Zezas, Vallia Antoniou, Despoina Hatzidimitriou The Small Magellanic Cloud (SMC) is well known to harbor a large number of High-Mass X-ray Binaries (HMXBs). The identification […]
