Ignition latitude and the shape of Type I X-ray bursts [PDF]

open access: yes, 2007
The shape of the lightcurve during the rising phase of Type I X-ray bursts is determined by many factors including the ignition latitude, the accretion rate, and the rotation rate of the star. We develop a phenomenological model of the burst rise process

A Critical Analysis of the Oxy-Combustion Process: From Mathematical Models to Combustion Product Analysis

open access: yesEnergies, 2022
Fossil fuels are the most widely used resource for energy production. Carbon dioxide (CO2) emissions are correlated with climate change, and therefore these emissions must be reduced in the future.
