Aims. Luminosity bursts in young FU Orionis-type stars warm up the surrounding disks of
gas and dust, thus inflicting changes on their morphological and chemical composition. In …

Direct imaging observations of planets revealed that wide-orbit (> 10 au) giant planets exist
even around subsolar-metallicity host stars and do not require metal-rich environments for …

Context. The picture of pre-main-sequence evolution is often simplified by the application of
classical initial models. Such models have large initial radii and sufficient uniform …

Cosmic metallicity evolution possibly creates the diversity of star formation modes at different
epochs. Gravitational fragmentation of circumstellar discs provides an important formation …

We present the analysis of the properties of large samples of protostellar discs formed in four
radiation hydrodynamical simulations of star cluster formation. The four calculations have …

We study the gravitational fragmentation of circumstellar discs accreting extremely metal-
poor () gas, performing a suite of 3D hydrodynamic simulations using the adaptive mesh …

Context. Diverse studies have shown that it is important to consider the impact of metallicity
on the chemodynamical evolution of protoplanetary disks. It has been suggested that there …

A protoplanetary disk (PPD) typically forms a dead zone near its midplane at a distance of a
few astronomical units from the central protostar. Accretion through such a magnetically …

In the context of planet formation, growth from micron-sized grains to kilometer-sized
planetesimals is a crucial question. Since the dust growth rate depends on the amount of …

The paper presents one construction of a Godunov-type method based on the separation of
operators describing the work of pressure forces and advective transfer. Separate …
