Good things come to those who wait: Watching donor stars evolve towards a mass-transfer instability
Unstable mass transfer in binary systems can lead to transients such as luminous red novae (LRNe). Observations of such transients are valuable for understanding and testing models of mass transfer. For donor stars in the Hertzsprung gap, there can be a long phase of mass-transfer evolution before instability sets in. Only few case studies of such delayed dynamical instability (DDI) mass transfer exist. None consider the full pre-instability evolution and the effects thereof on the observable p…

Inefficient dust production in a massive, metal-rich galaxy at $z=7.13$ uncovered by JWST and ALMA
Recent observations have revealed a remarkably rapid buildup of cosmic dust in the interstellar medium (ISM) of high redshift galaxies, with complex dust compositions and large abundances already appearing at redshifts $z>6$. Here we present a comprehensive, joint analysis of observations taken with the {\em James Webb Space Telescope} (JWST) and the Atacama Large Millimetre/sub-millimetre Array (ALMA) of the highly magnified, dusty `normal' galaxy, A1689-zD1 at $z=7.13$. We perform detailed sp…

Okay, also wir haben nicht nur ein Problem an #Silvester, sondern nun auch eines zu #Halloween. Die #Chaoten suchen neue Möglichkeiten,

Vorfall in Mittelfranken - Nagel in Halloween-Süßigkeit gefunden
Eine Mutter macht eine gefährliche Entdeckung: In einer Halloween-Süßigkeit ihrer Tochter steckt ein Nagel. Die Polizei ermittelt. Im Rest Bayerns blieb die Nacht weitgehend ruhig.
