uncertainties, such that any deviations in the parameter values due to an incorrect Ecutoff are not significant. The non- ionized reflector is likely located at a large distance from the black hole, e.g. the outer ...
for ionization by electron impact , fails to describe the underlying mechanisms existing in inelastic collisions with hydrogen (Barklem et al. 2011), as it is well established that inelastic transitions occur ...
be derived, for a simple case, by first considering the change in velocity of a mass m1, initially at rest, due to an encounter with a second mass m2 at a relative velocity |$v$| with impact parameter p ...
and their isotopologues. We demonstrate that non-LTE effects due to the strong continuum are significant. Abundance patterns are consistent with line formation in regions of carbon and oxygen depletions with nitrogen ...
observations The X-ray data consist of imaging from the Chandra ACIS-S3 CCD detector. ACIS-S3 has high quantum efficiency (QE; 0.8 at 1 keV), high spectral resolution (120 eV), high angular resolution of 1 ...
and the fully 13C-labelled ion were also determined. As the parent ion of MBO is not present in significant amounts due to extensive fragmentation during electron impact ionization in the GC-MS, we used a major ...
star. Given the focus on the simulation development and validation, dispersive influences due to warm plasma and the quantum magnetic vacuum will be neglected, their treatment being deferred to future ...
( due to efficient recombination cooling), gas will only be pushed above this temperature by feedback or a virial shock, and will usually persist well above or below this temperature (Brooks et al. 2009 ...
. They act as cooling agents in star-forming gas clouds and as catalysts for formation of the molecules, such as H2, that do not form efficiently in the gas phase (Cazaux & Tielens 2002). Grains are also ...
of τB − C ∼ 1023 s at T = 10 K (Cuppen & Herbst 2007). However, this time-scale estimate overestimates τB − C, since quantum tunnelling of hydrogen is more efficient than thermal hopping at 10 K. Using ...
