, 2002 We report the detection of the 405 nm band of interstellar C3 in absorption toward HD 210121. The abundance of triatomic carbon is approximately 1/17 of that of diatomic carbon in the same diffuse molecular cloud. Rotational levels of C3 up to $J=14$ are

Photon transport in a time-dependent interstellar cloud
, 2010 Photon transport is studied in an interstellar cloud occupying a time-dependent region V(t) ⊂ R^3 . First, under the assumption that the surface $\partial V(t)$ is a known function of t ∈ [0, tmax ], a direct problem is set and proof of well-posedness is

Cloud-cloud collisions in the interstellar medium
The Astrophysical Journal, 1980 Results are presented from time-dependent numerical simulations of cloud-cloud collisions in the interstellar medium. Special emphasis is placed on physically detailed models of cloud collisions. The numerical simulations include heating, cooling, thermal conductivity, self-gravity, and molecule formation; magnetic fields have been neglected.

Lower mass limit of an evolving interstellar cloud and chemistry in an evolving oscillatory cloud
, 1986 Simultaneous solution of the equation of motion, equation of state and energy equation including heating and cooling processes for interstellar medium gives for a collapsing cloud a lower mass limit which is significantly smaller than the Jeans mass for ...

Interaction of Supernova Reminants with Interstellar Cloud: Experiments on the Nova Laser
, 2002 The interaction of strong shock waves, such as those generated by the explosion of supernovae with interstellar clouds, is a problem of fundamental importance in understanding the evolution and the dynamics of the interstellar medium (ISM) as it is ...

Terrestrial atmospheric effects induced by counterstreaming dense interstellar cloud material
, 2004 The Solar System during its life has travelled more than 10 times through dense interstellar clouds with particle concentrations of $10^2{-}10^3$ ${\rm {cm^{-3}}}$ and more, compressing the heliosphere to heliopause dimensions smaller than 1 AU and ...

Measurements and Comparisons of Diffuse Interstellar Bands around the MBM12 Interstellar Cloud
, 2016 The interstellar medium is full of cool clouds, around 100°K, made of atoms, molecules, and dust particles. Mysterious components of these clouds are carriers of diffuse, unidentified interstellar bands (DIBs).
