Dynamical mass of the Serpens intermediate-mass young stellar system EC\,95 with DYNAMO--VLBA

Jazmín Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +8

We present dynamical mass measurements, obtained from multi-epoch Very Long Baseline Interferometry (VLBI) observations, for the young multiple stellar system EC\,95, located in th…

Luminosity distance and extinction by submicrometer-sized grains

Ralf Siebenmorgen, Frank Heymann, Rolf Chini

The distance to the stars is a fundamental parameter, which is determined via two primary methods - parallax and luminosity. While the parallax is a direct trigonometric method, th…

On the Origin of Fast Rotating Stars. I. Photometric calibration and results of AO-assisted BVRI+Halpha imaging of NGC330 with SAMI/SOAR

Felipe Navarete, Pedro Ticiani dos Santos, Alex Cavaliéri Carciofi +1

H emission is a clear indicator of circumstellar activity in Be stars, historically employed to assess the classical Be star (CBe) population in young open clusters (YOCs). The…

Interstellar Polarization Survey. IV. Characterizing the magnetic field strength and turbulent dispersion using optical starlight polarization in the diffuse interstellar medium

Y. Angarita, M. J. F. Versteeg, M. Haverkorn +5

Angular dispersion functions are typically used to estimate the fluctuations in polarization angle around the mean magnetic field orientation in dense regions, such as molecular cl…
