S. Molinari, NEAR-INFRARED VARIABILITY ((1-DIVIDED-BY-10) MU-M) OF HERBIG-HARO EXCITING SOURCES, Nuovo cimento della Societa italiana di fisica. C, Geophysics and space physics, 15(6), 1992, pp. 1033-1038
We present the preliminary results of a systematic study intended for
monitoring the photometric variations in the near IR ((1 divided-by 10
) mum), exhibited by young sources responsible of considerable mass lo
ss traced by Herbig-Haro (HH) objects, which are condensation of matte
r excited by interaction between the stellar wind and the circumstella
r environment. Comparing the observed spectral shape variations with t
hose predicted by models, positive indications in favour of accretion
phenomena occurring in disks can be derived.
