SALT spectroscopy of evolved massive stars
A. Y. Kniazev, V. V. Gvaramadze, L. N. Berdnikov
Long-slit spectroscopy with the Southern African Large Telescope (SALT) of central stars of mid-infrared nebulae detected with the Spitzer Space Telescope and Wide-field Infrared S…
Investigation of open clusters based on IPHAS and APASS survey data
Andrei Dambis, Elena Glushkova, Leonid Berdnikov +2
We adapt the classical Q-method based on a reddening-free parameter constructed from three passband magnitudes to thwe filter set of IPHAS survey and combine it with the maximum-li…
Discovery of a new Galactic bona fide luminous blue variable with Spitzer
V. V. Gvaramadze, A. Y. Kniazev, L. N. Berdnikov +3
We report the discovery of a circular mid-infrared shell around the emission-line star Wray 16-137 using archival data of the Spitzer Space Telescope. Follow-up optical spectroscop…
On the Crucial Cluster Andrews-Lindsay 1 and a 4% Distance Solution for its PN
D. Majaess, G. Carraro, C. Moni Bidin +5
Andrews-Lindsay 1 is a pertinent open cluster granted it may host the planetary nebula PHR 1315-6555, yet ambiguities linger concerning its fundamental parameters (>50% scatter). N…
