Oscillatory instability of radiative shocks with multiple cooling processes [PDF]
, 2003 The stand-off shock formed in the accretion flow on to a stationary wall, such as the surface of a white dwarf, may be thermally unstable, depending on the cooling processes which dominate the post-shock flow.

Symmetric Atom–Atom and Ion–Atom Processes in Stellar Atmospheres
Atoms, 2017 We present the results of the influence of two groups of collisional processes (atom–atom and ion–atom) on the optical and kinetic properties of weakly ionized stellar atmospheres layers.

Modelling transport processes in stellar radiative interiors
EPJ Web of Conferences, 2015 I report here on the different transport processes redistributing angular momentum and nuclides in stellar radiative interiors and on their modelling in stellar evolution codes.

Boundary effects on radiative processes of two entangled atoms [PDF]
, 2016 We analyze radiative processes of a quantum system composed by two identical two-level atoms interacting with a massless scalar field prepared in the vacuum state in the presence of perfect reflecting flat mirrors. We consider that the atoms are prepared

International Journal of Modern Physics D, 2010 Relativistic jets and collimated outflows are ubiquitous phenomena in astrophysical settings, from young stellar objects up to Active Galactic Nuclei. The observed emission from some of these jets can cover the whole electromagnetic spectrum, from radio to gamma-rays.

Infra-red radiative corrections for resonant processes [PDF]
Il Nuovo Cimento A, 1969 The infra-red radiative corrections to be applied to electron colliding beam experiments are given a nonperturbative treatment, which extends the method of ref. (2) to processes which take place through an intermediate resonant state,i.e. for which the high and low energy aspects can no longer be assumed to be separable. The resulting correction factor

A Theoretical Study of Temperature-dependent Photodissociation Cross Sections and Rates for O2
The Astrophysical Journal Supplement Series, 2023 The photodissociation of O _2 is thought to play a vital role in blocking UV radiation in the Earth’s atmosphere and likely has great importance in characterizing exoplanetary atmospheres.

Radiative processes in external gravitational fields
, 2010 Kinematically forbidden processes may be allowed in the presence of external gravitational fields. These ca be taken into account by introducing generalized particle momenta. The corresponding transition probabilities can then be calculated to all orders

Radiative Transfer Modeling of Phytoplankton Fluorescence Quenching Processes
Remote Sensing, 2018 We report the first radiative transfer model that is able to simulate phytoplankton fluorescence with both photochemical and non-photochemical quenching included.
