Mass loss is a key physical process in the evolution of massive stars, the impact of which propagates into galactic evolution, population synthesis models, the interpretation of high-redshift galaxies, and explosive events such as supernovae. However, there are currently substantial uncertainties in the low-metallicity, low-luminosity thin wind

Near-Earth asteroids (NEAs) offer unique laboratories for probing the internal structure and cohesion of small bodies. Although most asteroids spin more slowly than the so‑called "cohesionless spin barrier" (a ∼2.2 h rotation period above which a rubble pile would disrupt), a growing handful of NEAs exhibit much shorter periods, calling into

DG CVn is an eruptive variable star and represents the closest member of the known sample of complex periodic variables, or scallop-shell stars. Over the years, this M dwarf binary system has shown significant flaring activity at a wide range of frequencies. Here, we present a detailed analysis of ∼14 hours of radio observations of this stellar

This paper is the second in a series presenting the catalogs and properties of the largest sample to date of ∼100,000 star clusters and compact associations, in 38 spiral galaxies observed by the PHANGS-HST Treasury survey. Here, we present spectral energy distribution (SED) fitting techniques used to compute the age, mass, and reddening for each

One of the major achievements of planetary science in the past century has been the discovery of a population of asteroids and comets that have the potential to impact our planet. These objects are collectively known as Near-Earth Objects (NEOs), which include both asteroids and comets whose orbits bring them within 1.3 astronomical units (au) of

The ESA Hera Planetary Defence mission was sucessfully launched from Cape Cañaveral in October 7, 2024, with the goal of studying in detail the near-Earth binary asteroid system (65803) Didymos-Dimorphos[1]. The smaller of the two objects, asteroid Dimorphos, was impacted by the NASA DART spacecraft in September 26, 2022, as part of the first test
