Photometric and spectroscopic variations of the Be star HD 112999
M. A. Corti, R. C. Gamen, Y. J. Aidelman +2
Be objects are stars of B spectral type showing lines of the Balmer series in emission. The presence of these lines is attributed to the existence of an extended envelope, disk typ…
The interstellar medium and the massive stellar content toward the SNR G18.1-0.1 and neighboring HII regions
S. Paron, W. Weidmann, M. E. Ortega +2
We perform a multiwavelength study toward the SNR G18.1-0.1 and nearby several HII regions (infrared dust bubbles N21 and N22, and the HII regions G018.149-00.283 and G18.197-00.18…
Near-infrared photometry of Galactic planetary nebulae with the VVV Survey
W. A. Weidmann, R. Gamen, P. A. M. van Hoof +3
Planetary nebulae (PNe) are powerful tracers of evolved stellar populations. Among the 3000 known PNe in the Galaxy, about 600 are located within the 520 square-degree area covered…
