The mass distribution of these things can be estimated using functions named for Kroupa or Miller-Scalo.
The mass distribution of these things can be estimated using functions named for Kroupa or Miller-Scalo. These objects are typically studied using the infrared spectrum, because visible light is absorbed by the matter surrounding them. These objects were originally proposed to compose Herbig-Haro objects, which are now known to be the shockwaves caused by their older counterparts. They form when the critical Jeans length is reached. These objects are still surrounded by a ring of gas and dust, which is blown away when they start following the Hayashi and Henyey tracks. They form where a molecular cloud undergoes gravitational collapse. For 10 points, name these very young objects that have just started becoming stars.
