Important processes also occur in the atmospheres and winds themselves. These processes include shock-shock interaction and the "sudden" onset of molecule and dust formation which usually occurs in a highly stochastic naba-hairstreak.com by: These data sets also enabled greater detail to be measured of the mid-eclipse enhancement of the He I 10 Å line, and the discovery of the P Cygni shape of the Pa β line at the third contact.

We found evidence of higher speed material, associated with the mass transfer stream, persisting between third and fourth eclipse contacts. Jan 09,  · As low- and intermediate-mass stars reach the asymptotic giant branch (AGB), they have developed into intriguing and complex objects that are major players in the cosmic gas/dust cycle.
