▪ Abstract Radio astronomy has provided evidence for the presence of ionized atmospheres around almost all classes of nondegenerate stars. Magnetically confined coronae dominate in the cool half of the Hertzsprung-Russell diagram. Their radio emission is predominantly of nonthermal origin and has been identified as gyrosynchrotron radiation from mildly relativistic electrons, apart from some coherent emission mechanisms. Ionized winds are found in hot stars and in red giants. They are detected… Expand
Radio Emission from the Sun and Stars: New Insights into Energetic Phenomena
Energetic phenomena on the Sun and late-type stars pose a number of fascinating puzzles. These include coronal heating, flares, and coronal mass ejections, all believed to be manifestations ofExpand
Radio Emissions from Substellar Companions of Evolved Cool Stars
A number of substellar companions to evolved cool stars have now been reported. Cool giants are distinct from their progenitor main-sequence low-mass stars in a number of ways. First, the mass lossExpand
Radio Emission from Ultra-Cool Dwarfs
The 2001 discovery of radio emission from ultra-cool dwarfs (UCDs), the very low-mass stars and brown dwarfs with spectral types of ~M7 and later, revealed that these objects can generate andExpand
Physical Processes in Magnetically Driven Flares on the Sun, Stars, and Young Stellar Objects
The first flare on the Sun was observed exactly 150 years ago. During most of the long history, only secondary effects have been noticed, so flares remained a riddle. Now the primary flare products,Expand
AGN coronal emission models – I. The predicted radio emission
Accretion discs in AGN may be associated with coronal gas, as suggested by their X-ray emission. Stellar coronal emission includes radio emission, and AGN corona may also be a significant source forExpand
The Origin of the Galactic Center Nonthermal Radio Filaments: Young Stellar Clusters
The unusual class of magnetized nonthermal radio filaments, threads, and streaks, with their unique physical characteristics, is found only within the inner couple of degrees of the Galactic center.Expand
Many low-mass pre-main-sequence stars exhibit strong magnetic activity and coronal X-ray emission. Even after the primordial accretion disk has been cleared out, the star's high-energy radiationExpand
Transient Emissions from Radio-Active Stars: Implications for Wide-Field Radio Surveys
Variability is a common characteristic of magnetically active stars. Flaring variability is usually interpreted as the observable consequence of transient magnetic reconnection processes happening inExpand
Radio eclipses of exoplanets by the winds of their host stars
The search for exoplanetary radio emission has resulted in zero conclusive detections to date. Various explanations for this have been proposed, from the observed frequency range, telescopeExpand
Detection of α Centauri at radio wavelengths: chromospheric emission and search for star-planet interaction
At radio wavelengths, solar type stars emit thermal free-free and gyroresonance, gyrosynchrotron, and impulsive coherent emission. Thermal free-free emission originates at layers where the opticalExpand


Compact non-thermal radio emission from B-peculiar stars
Some stars hotter than 10,000 K show propensity for unusual surface abundances and excessive magnetic fields. These peculiar stars, Ap and Bp in the spectral nomenclature, show unusually prominentExpand
Atmospheric Heating and Quiescent Radio Emission in Active Stars
Surveys of magnetically active stars of K to M spectral classes have revealed an interrelationship between their "quiescent" soft X-ray (SXR) and microwave luminosities. While the quiescent SXRExpand
Circularly Polarized Radio Emission from an X-Ray Protostar
IRS 5, an embedded young stellar object in the nearby Corona Australis molecular cloud, was recently detected as an X-ray source with the ASCA and ROSAT satellites. We report here the detection ofExpand
Radio-Frequency Continuum Emission from Evolved Stars
2 Abstract The evolution of stars between the AGB and planetary nebula phases was investigated by sensitive radio continuum observations of a sample of 21 evolved stars with high mass loss rates andExpand
Discovery of radio emission from the brown dwarf LP944-20
It is shown that LP944-20 has an unusually weak magnetic field in comparison to active M-dwarf stars, which might explain the previous null optical and X-rays results, as well as the strength of the radio emissions compared to those at X-ray wavelengths. Expand
Non-thermal emission in Wolf-Rayet stars: are massive companions required?
We examine the radio spectral indices of 23 Wolf–Rayet (WR) stars to identify the nature of their radio emission. We identify nine systems as non-thermal emitters. In seven of these systems theExpand
The ionized wind of IRAS 08159-3543
We report the detection of cm radio emission from the ionized wind which had been suggested to exist in the inner part of the bipolar outflow around the embedded Young Stellar Object (YSO) IRASExpand
The collective radio properties of symbiotic stars
Radio measurements of symbiotic stars are reported which extend the search for radio emission and provide multifrequency and multiepoch measurements of previously detected stars. The results show noExpand
Radio evidence for nonthermal particle acceleration on stars of late spectral type
Radio evidence for nonthermal particle acceleration on stars of late spectral type (G, K, and M) is reviewed, including the pre-main-sequence T Tauri stars, the dwarf M flare stars, and the RS CVnExpand
Radio Emission from ROSAT-discovered Young Stars in and around Taurus-Auriga
An 8.4 GHz VLA survey of 91 recently discovered lithium-rich late-type stars from the ROSAT All-Sky Survey and pointed observations is presented. These objects lie in the vicinity of theExpand
