The FRIGG project: From intermediate galactic scales to self-gravitating cores

, 2017
Abridged. Understanding the detailed structure of the interstellar gas is essential for our knowledge of the star formation process. The small-scale structure of the interstellar medium (ISM) is a direct consequence of the galactic scales and making the ...

Episodic accretion, protostellar radiative feedback, and their role in low-mass star formation

, 2012
Protostars grow in mass by accreting material through their discs, and this accretion is initially their main source of luminosity. The resulting radiative feedback heats the environments of young protostars, and may thereby suppress further ...

Can magnetized turbulence set the mass scale of stars? [PDF]

, 2020
Understanding the evolution of self-gravitating, isothermal, magnetized gas is crucial for star formation, as these physical processes have been postulated to set the initial mass function (IMF). We present a suite of isothermal magnetohydrodynamic (MHD)

Autocollimating compensator for controlling aspheric optical surfaces

, 2014
A compensator (null-corrector) for testing aspheric optical surfaces is proposed, which enables i) independent verification of optical elements and assembling of the compensator itself, and ii) ascertaining the compensator position in a control layout ...

The Role of Gravity in Producing Power-Law Mass Functions [PDF]

, 2018
Numerical simulations of star formation have found that a power-law mass function can develop at high masses. In a previous paper, we employed isothermal simulations which created large numbers of sinks over a large range in masses to show that the power

The Formation of Low-Mass Binary Star Systems Via Turbulent Fragmentation

, 2010
We characterize the infall rate onto protostellar systems forming in self-gravitating radiation-hydrodynamic simulations. Using two dimensionless parameters to determine disks' susceptability to gravitational fragmentation, we infer limits on ...

Star Cluster Formation in Turbulent, Magnetized Dense Clumps with Radiative and Outflow Feedback [PDF]

, 2014
We present three Orion simulations of star cluster formation in a 1000 Msun, turbulent molecular cloud clump, including the effects of radiative transfer, protostellar outflows, and magnetic fields.

Interactions between brown-dwarf binaries and Sun-like stars

, 2012
Several mechanisms have been proposed for the formation of brown dwarfs, but there is as yet no consensus as to which -- if any -- are operative in nature. Any theory of brown dwarf formation must explain the observed statistics of brown dwarfs.

The Gaia-ESO Survey: N-body modelling of the Gamma Velorum cluster [PDF]

, 2015
The Gaia-ESO Survey has recently unveiled the complex kinematic signature of the Gamma Velorum cluster: this cluster is composed of two kinematically distinct populations (hereafter, population A and B), showing two different velocity dispersions and a ...

Algorithm Theoretical Basis for Version 3 TEMPO Level 0–1 Processor

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument is the first spaceborne hyperspectral spectrometer that measures backscattered sunlight over North America in a geostationary orbit. The two charge‐coupled device (CCD) detectors of TEMPO, with spectral coverages of 293–494 and 538–741 nm and resolutions of 0.53–0.63 nm ...
