The first systematic, quantitative appraisal of power density, offering detailed reviews of
power densities of renewable energy flows, fossil fuels, and all common energy …

A primary goal of the Parker Solar Probe (PSP) Mission is to answer the outstanding
question of how the solar corona plasma is heated to the high temperatures needed for the …

We analyze the dynamics of the Sun-Earth-Moon system in the context of a particular class
of theories of gravity where curvature and matter are nonminimally coupled. These theories …

We have previously reported on models of low-mass stars in which the presence of inflated
radii is ascribed to magnetic fields that impede the onset of convection. Some of our …

We present the analyses of intense X-ray flares detected on the active fast rotator AB Dor
using observations from the XMM–Newton. A total of 21 flares are detected, and 13 flares …

The Rotation–activity Correlations in K and M Dwarfs. II. New Constraints on the Dynamo
Mechanisms in Late-K and M Dwarfs before and at the Transition to Complete Convection …

Modeling the behavior of magnetohydrodynamic waves in a range of magnetic geometries
mimicking solar atmospheric waveguides, from photospheric flux tubes to coronal loops, can …

Of all types of solar collector, the flat-plate collector (FPC) has the lowest performance, but is
the most widely used because of its low cost and easy maintenance. To effectively collect …

The results of a search for stellar pulsations in M dwarf stars in the Kepler short-cadence
(SC) data base are presented. This investigation covers all the cool and dwarf stars in the list …

Observations of solar and stellar flares have revealed the presence of power-law
dependences between the flare energy and the time interval between flares. Various models …
