Main Sequence Stars

In Search of Temperature Minimum at Radio Wavelengths
Introduction Our ability to infer the physical characteristics of stellar atmospheres largely depends on our understanding of the emissions from stars at sub-millimeter to centimeter wavelengths. Unfortunately, the technical difficulty in observing main sequence stars at these wavelengths has delayed research in this area.

The MESAS Project: ALMA Observations of the F-type Stars γ Lep, γ Vir A, and γ Vir B
We present Atacama Large Millimeter/submillimeter Array observations of the three nearby, main-sequence, debris-poor, F-type stars γ Lep, γ Vir A, and γ Vir B at 0.87 and 1.29 mm.

Nonlinear Convergence of Solar-like Stars Chromospheres Using Millimeter, Submillimeter, and Infrared Observations
In this work, we present a new methodology to fit the observed and synthetic spectrum of main-sequence stars through semiempirical models.

ALMA's view of the nearest neighbors to the Sun. The submm/mm SEDs of the α Centauri binary and a new source
The precise mechanisms that provide the nonradiative energy for heating the chromosphere and corona of the Sun and other stars are at the focus of intense contemporary research.
