A search for 43.122 GHz SiO emission from symbiotic stars.
Abstract
During the second half of 1986 tests were made of a new Q-band (43 GHz) receiver designed for the Parkes radio telescope. As part of the trial observation program 12 symbiotic stars were examined for SiO maser emission. No significant new emission was detected from any of the candidates, although several previously known SiO sources (including one symbiotic star) were confirmed. The authors conclude that potential SiO maser action near the Mira star in most symbiotic systems is prevented by the presence of the hot companion star.
