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.

The MESAS Project: Long-wavelength Follow-up Observations of Sirius A

Here we present Atacama Large Millimeter/submillimeter Array, Green Bank Telescope, and Very Large Array observations of Sirius A, the closest main-sequence A-type star, that span from 1.4 to 9.0 mm.

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.
