Stellar Radio Astronomy. Probing Stellar Atmospheres from Protostars to Giants
Annual Review of Astronomy and Astrophysics, 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 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.

Extragalactic Stellar Astronomy [PDF]
, 2008 Despite their paucity, massive hot stars are real cosmic engines of fundamental importance in shaping our Universe, from its very early stages up to its current appearance. Understanding the physics of massive stars is then a key issue for many relevant astrophysical phenomena.

Lithium in Turnoff Stars in the Globular Cluster M5: A Quest for Primordial Lithium
The Astrophysical Journal, 2023 The light element lithium is formed by nucleosynthesis during the Big Bang. Its abundance can help to define the parameters of the early Universe. To find this primordial value, it is necessary to determine Li abundances in the oldest stars because it is
