... Discovery of enrichment of the envelopes of post-AGB stars with heavy metals . As a result of monitoring carried out at the BTA telescope, a new phenomenon was discovered in the optical spectra of post-AGB supergiants with an emission at 21 ?m and an overabundance of carbon and heavy metals in the atmospheres - the splitting of the strongest absorption lines. ... Thus, we discovered for the first time the enrichment of the stellar envelope with heavy metals synthesized by the s-process. ...

A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...

... The jets can also be produced in smaller scale by binary stellar systems. ... Some 200 -- 250 X-ray binaries, systems in which a neutron star or black hole is accreting material from a companion star, are known. Approximately 20% of these sources have been detected at radio wavelengths, and in several cases high resolution radio observations have resolved this emission into jet-like structures, sometimes with components moving at relativistic velocities. ... It is variable radio source. ...
