3D simulations of RS Oph: from accretion to nova blast
Rolf Walder, Doris Folini, Steven N. Shore
RS Ophiuchi is a recurrent nova with a period of about 22 years, consisting of a wind accreting binary system with a white dwarf (WD) very close to the Chandrasekhar limit and a re…
Supersonic turbulence in shock-bound interaction zones I: symmetric settings
Doris Folini, Rolf Walder
Colliding hypersonic flows play a decisive role in many astrophysical objects. In this paper, we look at the idealized model of a 2D plane parallel isothermal slab (CDL) and at sym…
Structuring and support by Alfven waves around prestellar cores
Doris Folini, Jean Heyvaerts, Rolf Walder
Observations of molecular clouds show the existence of starless, dense cores, threaded by magnetic fields. Observed line widths indicate these dense condensates to be embedded in a…
Complex wind dynamics and ionization structure in symbiotic binaries
Rolf Walder, Doris Folini
Aspects of the wind-dynamics in symbiotic binaries, colliding winds and accretion, are reviewed. Inconsistencies between theory and observations of the hot star wind are discussed.…
Theory of thermal and ionization effects in colliding winds of WR+O binaries
Doris Folini, Rolf Walder
The colliding winds interaction zone in WR+O binaries is a highly complex environment. In this review we summarize the progress made towards its theoretical understanding during th…
Radiative cooling instability in 1D colliding flows
Rolf Walder, Doris Folini
Radiative shock waves show a strong cooling instability at temperatures above approximately 2 times 10^5 K. We numerically investigate this instability by simulating different astr…
