T Tauri - Wikidocumentaries

The prototypical T Tauri star – T Tauri itself – is part of a close binary system with a smaller, fainter companion. This is visible in the high resolution infrared image below. T Tauri stars actually look quite similar to main sequence stars. Their surface temperatures are about the same as a star of a similar mass, but they’re more luminous because they have a larger An Interesting Neighborhood to Live In. The variable star T Tauri was discovered on an October night in 1852 by John Russell Hind. Hind, a noted asteroid hunter, is credited with having discovered 11 minor planets, as well as Nova Ophiuchi 1848 and R Leporis (also known as Hind's Crimson Star). Tianguan is a main star in the constellation Taurus and makes up the constellation outline. Based on the spectral type (B4IIIp) of the star, the star's colour is blue.

It ends when a star of 0.5 M☉ develops a radiative zone, or when a larger star commences nuclear fusion on the main sequence. The optical excess in T Tauri stars implies that the photospheric lines in these stars are not as deep as those of a main sequence star of the same spectral type. This effect, usually referred to as ``veiling'', as been studied mainly in the optical [ Basri & Batalha 1990 , Hartigan et al. 1991 , Guenther & Hessman 1993a , Valenti et al.

A star begins its life as a protostar still enveloped in its molecular cloud. Over the years the newborn st T-Tauri stars (the class is named after the first star of this type that was so identified) are less than about ten million years old, and provide astronomers with promising candidates in which to There’s evidence that T Tauri stars are covered with active sunspots, and they produce extremely powerful stellar winds. Some of the brightness we see from here on Earth is the T Tauri star’s We conclude that most T Tauri stars in our sample have experienced some degree of dust settling and grain growth in their disks, indicating disk evolution. We analyzed Spitzer Infrared Spectrograph data of a representative sample of classical T Tauri stars in the Taurus star-forming region by computing color indices in wave bands that characterize the continuum emission from dust in circumstellar disks.
