T-tauri-star meaning. T-tauri-star. meaning. (0) (astronomy) A class of young visible stars having optical variability; they are often surrounded by a protoplanetary disc. noun.

Eleven irregular variable stars have been observed whose physical characteristics seem much alike and yet are sufficiently different from other known classes of

They measured the temperature of the water vapor, which appeared to be 2000 K. T Tauri Star. [/caption] When a star is still in the earliest stages of formation, it doesn’t have enough temperature in its core to ignite fusion of hydrogen and helium. Instead, the star T Tauri stars are pre-main-sequence stars in the process of contracting to the main sequence along the Hayashi track, a luminosity-temperature relationship obeyed by infant stars of less than 3 solar masses in the pre-main-sequence phase of stellar evolution. T Tauri stars are the youngest visible F, G, K, M spectral type stars.

They are newly-formed (< 10 million years old) low to intermediate mass stars (< 3 solar masses) with central temperatures too low for nuclear fusion to have started. 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 T-Tauri stars are pre-main sequence stars that are named after the first starto be discovered T-Tauriin the constellation of Taurus. They are a young star and one that is a variable staras it can vary its size over time. A star start off as cloudsof dust and gas before something starts the process of turning that nebulainto a star. T Tauri stars take after their prototype T Tauri.

T Tauri is a variable star in the constellation Taurus, the prototype of the T Tauri stars.It was discovered in October 1852 by John Russell Hind.T Tauri appears from Earth amongst the Hyades cluster, not far from ε Tauri; but it is actually 420 light years behind it and was not formed with the rest of them.

T Tauri stars show outbursts of this kind, and so do FU Orionis stars, but FU Orionis spectra show absorption of light by calcium, whereas Object 50 shows emission by calcium. Object 50: a stellar quick-change artist We analyze 117 echelle spectra of the T Tauri star DF Tau, concentrating on variations in the optical continuum veiling and the strong emission lines. Although this star was the inspiration for the original suggestion of magnetospheric accretion in T Tauri stars (TTSs), this hypothesis is only partially supported in our data. Weak-lined T Tauri stars are so named because we only see weak emission lines from them, and Naked T Tauri stars have little or no excess continuum or line emission at all.
