T Tauri star

[′tē ′tȯr·ē ‚stär]
(astronomy)
A star, with mass from 0.5 to 2.5 solar masses, in an early stage of formation at which interaction with its associated nebulosity, as well as possible internal instabilities, make it variable in luminosity and render its spectrum very peculiar. Also known as nebular variable.

Thermal metamorphism was probably due to a combination of the following heat sources; the decay of short-lived radionuclides, electromagnetic induction during an early T-Tauri stage of the sun, or possibly the brecciated in situ target material being in proximity to an impact-generated melt sheet.
