The formation of protostars and their disks has been understood as the result of the
gravitational collapse phase of an accumulation of dense gas that determines the mass …

We model Pop III star formation in different FUV and X-ray backgrounds, including radiation
feedback from protostars. We confirm previous results that a moderate X-ray background …

We report on an Atacama Large Millimeter/submillimeter Array study of the Class I or II
intermediate-mass protostar DK Cha in the Chamaeleon II region. The 12 CO (J= 2–1) …

Context. Most massive stars are located in multiple stellar systems. The modeling of disk
fragmentation, a mechanism that may plausibly lead to stellar multiplicity, relies on parallel …

Context. Similar to their lower mass siblings, massive protostars can be expected to:(a) be
surrounded by circumstellar disks, and (b) launch magnetically driven jets and outflows. The …

Context. In spite of decades of theoretical efforts, the physical origin of the stellar initial mass
function (IMF) is still a subject of debate. Aims. We aim to gain an understanding of the …

Context. Due to the presence of magnetic fields, protostellar jets or outflows are a natural
consequence of accretion onto protostars. They are expected to play an important role in …

Recent millimeter/submillimeter facilities have revealed the physical properties of
filamentary molecular clouds in relation to high-mass star formation. A uniform survey of the …

Context. The fragmentation of high-mass star-forming regions depends on a variety of
physical parameters, including density, the magnetic field, and turbulent gas properties …

Context. Forming massive stars launch outflows of magnetic origin, which in fact serve as a
marker for finding sites of massive star formation. However, both the theoretical and …
