[HTML][HTML] A 200km/s molecular wind in the peculiar carbon star V Hya.
GR Knapp, A Jorissen, K Young�- Astronomy and Astrophysics�…, 1997 - adsabs.harvard.edu
A molecular wind with an outflow speed in excess of 200km/s has been found in the AGB
carbon star V Hya. Observations of several molecular lines show that the circumstellar
envelope is expanding at 15km/s and is flattened and inclined to the line of sight. The fast
wind appears to be expanding from the poles of the envelope, with the expansion speed
increasing with distance from the star. V Hya may be in the very earliest stage of evolution
beyond the AGB.
