Stellar Radio Astronomy. Probing Stellar Atmospheres from Protostars to Giants [PDF]

open access: green, 2002
Radio astronomy has provided evidence for the presence of ionized atmospheres around almost all classes of non-degenerate stars. Magnetically confined coronae dominate in the cool half of the Hertzsprung-Russell diagram.

Solving Stellar Astronomy Problems in the Orbital Stellar Stereoscopic Observatory Project

open access: hybridOpen Astronomy, 2015
We propose to establish an Orbital Stellar Stereoscopic Observatory (OStSO) consisting of two identically equipped spacecrafts (SCs) in the vicinity of two Lagrangian libration points, L4 and L5, of the “Sun – Earth+Moon barycenter” system.

Spectroscopic Follow-up of Gaia Exoplanet Candidates: Impostor Binary Stars Invade the Gaia DR3 Astrometric Exoplanet Candidates

open access: yesThe Astronomical Journal, 2023
In this paper, we report on the follow-up of six potential exoplanets detected with Gaia astrometry and provide an overview of what is currently known about the nature of the entire Gaia astrometric exoplanet candidate sample, 72 systems in total.

Constraints on Stellar Flare Energy Ratios in the NUV and Optical from a Multiwavelength Study of GALEX and Kepler Flare Stars

open access: yesThe Astrophysical Journal, 2023
We present a multiwavelength study of stellar flares on primarily G-type stars using overlapping time domain surveys in the near-ultraviolet (NUV) and optical regimes. The NUV (the Galaxy Evolution Explorer; GALEX) and optical (Kepler) wavelength domains

History of Astronomy in Australia: Big-Impact Astronomy from World War II until the Lunar Landing (1945–1969)

open access: yesGalaxies, 2021
Radio astronomy commenced in earnest after World War II, with Australia keenly engaged through the Council for Scientific and Industrial Research. At this juncture, Australia’s Commonwealth Solar Observatory expanded its portfolio from primarily studying
