Radio Stars in the Era of New Observatories

Lynn D. Matthews

An international conference Radio Stars in the Era of New Observatories was held at the Massachusetts Institute of Technology Haystack Observatory on 2024 April 17-19. The conferen…

HI line observations of 290 evolved stars made with the Nancay Radio Telescope -- I. Data

E. Gerard, W. van Driel, L. D. Matthews +3

We present a compendium of HI 21-cm line observations of circumstellar envelopes (CSEs) of 290 evolved stars, mostly (~84%) on the asymptotic giant branch (AGB), made with the 100m…

Detection of Rydberg lines from the atmosphere of Betelgeuse

W. R. F. Dent, G. Harper, A. M. S. Richards +2

Emission lines from Rydberg transitions are detected for the first time from a region close to the surface of Betelgeuse. The H30 line is observed at 231.905 GHz, with a FWHM ~4…

The Evolving Radio Photospheres of Long-Period Variable Stars

L. D. Matthews, M. J. Reid, K. M. Menten +1

Observations with the Karl G. Jansky Very Large Array at 46 GHz (7 mm) have been used to measure the size and shape of the radio photospheres of four long-period variable stars: R…

Revealing the structure of the outer disks of Be stars

R. Klement, A. C. Carciofi, T. Rivinius +9

Context. The structure of the inner parts of Be star disks (20 stellar radii) is well explained by the viscous decretion disk (VDD) model, which is able to reproduce the observable…

A Search for Mass Loss on the Cepheid Instability Strip using HI 21-cm Line Observations

L. D. Matthews, M. Marengo, N. R. Evans

We present the results of a search for HI 21-cm line emission from the circumstellar environments of four Galactic Cepheids (RS Pup, X Cyg, Gem, and T Mon) based on observation…
