A fast and robust recipe for modeling nonideal magnetohydrodynamic effects in star formation simulations

Context. Nonideal magnetohydrodynamic (MHD) effects are thought to be a crucial component of the star formation process. Numerically, several complications render the study of nonideal MHD effects in 3D simulations extremely challenging and hinder efforts ...

Ambipolar diffusion and the mass-to-flux ratio in a turbulent collapsing cloud

Aris Evangelos Tritsis

Context. The formation of stars is governed by the intricate interplay of nonideal magnetohydrodynamic (MHD) effects, gravity, and turbulence. Computational challenges have hindered a comprehensive 3D exploration of this interplay, posing a longstanding ch ...

Can we observe the ion-neutral drift velocity in prestellar cores?

Aris Evangelos Tritsis

Given the low-ionization fraction of molecular clouds, ambipolar diffusion is thought to be an integral process in star formation. However, chemical and radiative-transfer effects, observational challenges, and the fact that the ion-neutral drift velocity ...

CO enhancement by magnetohydrodynamic waves Striations in the Polaris Flare

Aris Evangelos Tritsis

Context. The formation of molecular gas in interstellar clouds is a slow process, but can be enhanced by gas compression. Magnetohydrodynamic (MHD) waves can create compressed quasi-periodic linear structures, referred to as striations. Striations are obse ...
