Constellations of satellites are being proposed in large numbers; most of them are expected
to be in orbit within the next decade. They will provide communication to unserved and …

Yearslong time series of high-precision brightness measurements have been assembled for
thousands of stars with telescopes operating in space. Such data have allowed astronomers …

Massive stars are important metal factories in the Universe. They have short and energetic
lives, and many of them inevitably explode as a supernova and become a neutron star or …

We present the first asteroseismic results for δ Scuti and γ Doradus stars observed in
Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data for a sample …

Numerous magnetic hot stars exhibit gyrosynchrotron radio emission. The source electrons
were previously thought to be accelerated to relativistic velocities in the current sheet formed …

Context. The lack of high-precision long-term continuous photometric data for large samples
of stars has impeded the large-scale exploration of pulsational variability in the OB star …

The convective envelopes of solar-type stars and the convective cores of intermediate-and
high-mass stars share boundaries with stable radiative zones. Through a host of processes …

Quantum communication is a prime space technology application and offers near-term
possibilities for long-distance quantum key distribution (QKD) and experimental tests of …

Classical novae are thermonuclear explosions that occur on the surfaces of white dwarf
stars in interacting binary systems. It has long been thought that the luminosity of classical …

Context. While rotation has a major impact on stellar structure and evolution, its effects are
not well understood. Thanks to high-quality and long-time base photometric observations …
