SS 433: The wiggle of the wind
, 2011 The Balmer H alpha emission line in the stationary spectrum of SS 433 has a component originating in the wind above the accretion disk. The Doppler motion of this line is a blurred representation of the motion of the compact object accreting.

Methane from UV-irradiated carbonaceous chondrites under simulated Martian conditions [PDF]
, 2012 A UV photolytic process was studied for the production of methane from carbonaceous chondrites under simulated Martian conditions. Methane evolution rates from carbonaceous chondrites were found to be positively correlated to temperature (−80 to 20°C ...

Microbial Endolithic Community at Meteor Crater
Meteoritics &Planetary Science, EarlyView.Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Impact of an asteroid or comet in the ocean and extinction of terrestrial life [PDF]
, 1983 Finite difference calculations describing the impact mechanics associated with a 10 to 30 km diameter silicate or water object impacting a 5 km deep ocean overlying a silicate solid planet demonstrate that from 12 to 15% of the bolide energy resides in ...

Physics of the Chelyabinsk bolide [PDF]
Astronomical School’s Report, 2013 Shown, that estimations of the Chelyabinsk body size order of 20–30 m (15/02/2013 phenomenon), publishing in the press, are overstated significantly. Estimations of its explosion height are wrong. On the basis of the destructions by action of the shock wave, the height of explosion must be no more than 10–12 km. We think, that the Chelyabinsk meteorite

Orbital evolution of P\v{r}\'{i}bram and Neuschwanstein
, 2011 The orbital evolution of the two meteorites P\v{r}\'{i}bram and Neuschwanstein on almost identical orbits and also several thousand clones were studied in the framework of the N-body problem for 5000 years into the past.
