The Effects of Spatio-temporal Resolution on Deduced Spicule Properties
Tiago M. D. Pereira, Bart De Pontieu, Mats Carlsson
Spicules have been observed on the sun for more than a century, typically in chromospheric lines such as H-alpha and Ca II H. Recent work has shown that so-called 'type II' spicule…
Quantifying Spicules
Tiago M. D. Pereira, Bart De Pontieu, Mats Carlsson
Understanding the dynamic solar chromosphere is fundamental in solar physics. Spicules are an important feature of the chromosphere, connecting the photosphere to the corona, poten…
Fast approximation of angle-dependent partial redistribution in moving atmospheres
Jorrit Leenaarts, Tiago Pereira, Han Uitenbroek
Radiative transfer modeling of spectral lines including partial redistribution (PRD) effects requires the evaluation of the ratio of the emission to the absorption profile. This qu…
