JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR

M. Elyajouri, A. Abergel, N. Ysard +19

Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…

JWST observations of photodissociation regions: II. Warm molecular Hydrogen spectroscopy in the Horsehead nebula

M. Zannese, P. Guillard, A. Abergel +16

H2 is the most abundant molecule in the interstellar medium and is a useful tool to study photodissociation regions, where radiative feedback from massive stars on molecular clouds…

PDRs4All XIX. The 6 to 9 m region as a probe of PAH charge and size in the Orion Bar

Baria Khan, Samuel A. Daza Rodriguez, Els Peeters +24

Infrared emission from polycyclic aromatic hydrocarbons (PAHs) play a major role in determining the charge balance of their host environments that include photo-dissociation region…

V659 Cen: System Parameters Updated

Nancy Remage Evans, Charles Proffitt, Pierre Kervella +8

V659 Cen is a classical Cepheid which is part of a multiple system. Previous observations have shown that a hot companion dominates an ultraviolet spectrum and a cooler main sequen…

Mass of Cepheid V350 Sgr Incorporating Interferometry and the Companion Mass

Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella +8

The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system and the full orbit is determined. The mass of the companion has been determi…
