Physical parameters of red supergiants in dwarf irregular galaxies in the Local Group
N. E. Britavskiy, A. Z. Bonanos, A. Herrero +6
Increasing the statistics of evolved massive stars in the Local Group enables investigating their evolution at different metallicities. During the late stages of stellar evolution,…
Mid-infrared evolution of eta Car from 1968 to 2018
A. Mehner, W. -J. de Wit, D. Asmus +6
Eta Car is one of the most luminous and massive stars in our Galaxy and is the brightest mid-infrared (mid-IR) source in the sky, outside our solar system. Since the late 1990s the…
Elemental abundances in the remnant of the ancient eruption of CK Vulpeculae
R. Tylenda, T. Kamiński, A. Mehner
CK Vul or Nova 1670 is an enigmatic eruptive object which underwent a stellar-merger event recorded by seventeenth-century observers. Its remnant was recently recovered at submilli…
Rotational and rotational-vibrational Raman spectroscopy of air to characterize astronomical spectrographs
F. P. A. Vogt, F. Kerber, A. Mehner +14
Raman scattering enables unforeseen uses for the laser guide-star system of the Very Large Telescope. Here, we present the observation of one up-link sodium laser beam acquired wit…
A massive nebula around the Luminous Blue Variable star RMC143 revealed by ALMA
Claudia Agliozzo, Andrea Mehner, Neil Matthew Phillips +11
The luminous blue variable (LBV) RMC143 is located in the outskirts of the 30~Doradus complex, a region rich with interstellar material and hot luminous stars. We report the s…
