Impacts of the PAH size and the radiation intensity on the IR features of illuminated dust within the reflection nebulae
Gadallah, Kamel A. K.; Ali, Abdallah A. M.
Interstellar dust grains are illuminated in the reflection nebulae. Under conditions of the PAH size and the intensity of the interstellar radiation field, we follow their impact on the PAH aromatic infrared bands using the numerical DustEM code. For a dust model consisting of PAH, amorphous C and amorphous silicate, the PAH size varies in a range…
Small Bodies Near and Far (SBNAF): A benchmark study on physical and thermal properties of small bodies in the Solar System
Marton, G.; Müller, T. G.; Alí-Lagoa, V. +15 more
The combination of visible and thermal data from the ground and astrophysics space missions is key to improving the scientific understanding of near-Earth, main-belt, trojans, centaurs, and trans-Neptunian objects. To get full information on a small sample of selected bodies we combine different methods and techniques: lightcurve inversion, stella…
ISO: highlights of recent results
Salama, A.
The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four versatile scientific instruments, it was launched by an Ariane 44P in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the universe at infrare…
