Abstract Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its
scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to …

Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and
evolution, regulating star formation, shaping the stellar mass function and the mass …

Debris disks are optically thin, almost gas-free dusty disks observed around a significant
fraction of main-sequence stars older than about 10 Myr. Since the circumstellar dust is short …

We present the dust ejecta of the new stellar models for the thermally pulsing asymptotic
giant branch (TP-AGB) phase computed with the colibri code. We use a formalism of dust …

Vega and Fomalhaut are similar in terms of mass, ages, and global debris disk properties;
therefore, they are often referred to as" debris disk twins." We present Spitzer 10–35 μm …

Context. Dust is expected to be ubiquitous in extrasolar planetary systems owing to the
dynamical activity of minor bodies. Inner dust populations are, however, still poorly known …

Context. In 1929, Russell predicted that dust particles cannot survive in a region close to any
star, hence giving justification for a dust free zone to exist inside a certain distance from the …

Context. Stars in the solar neighbourhood have refractory element ratios slightly different
from that of the Sun. It is unclear how much the condensation of solids and thus the …

Context. Millimeter astronomy provides valuable information on the birthplaces of planetary
systems. In order to compare theoretical models with observations, the dust component has …

Dust particles in orbit around a star drift toward the central star by the Poynting-Robertson
effect and pile up by sublimation. We analytically derive the pile-up magnitude, adopting a …
