H 212 is a nearby star system about 1,300 light years away in Orion. The central protostar, or forming star, in HH212 is only about 40,000 yrs old (which is about 10 millionth of the age of Our Sun). It drives a powerful bipolar jet. Previous searches hinted at the existence of a small dusty disk near the protostar. Now with ALMA, with 25 times higher resolution, we detect and detail a dusty disk at submillimeter wavelength.
The disk is nearly edge-on and has a radius of about 60 Astronomical Units. Interestingly, it shows a prominent equatorial dark lane sandwiched between two brighter features, due to relatively low temperature and high optical depth near the disk midplane. The structure of the dark lane clearly implies that the disk is flared, as expected in an accretion disk model.
