temperature: A measure of the velocity of random motions among the atoms or molecules in a material. Most T Tauri stars in Taurus have luminosities 1 L, and irradiation heating leads to a typical disk temperature T d 10 K at 100 AU (D'Alessio et al. 1998). (This is also consistent with observational estimates from spectral energy distributions of typical T Tauri stars, as indicated by the results of BSCG .)

It is the prototype of the T Tauri stars. These young stars have surface temperatures similar to those of main-sequence stars of the same mass, but they are significantly more luminous because their radii are larger.

Om avståndet, d, kan mätas, t.ex. med parallax, så kan luminociteten, L, hos stjärnan bestämmas. T Tauri stars comprise the youngest visible F, G, K and M spectral type stars (<2 M☉). Their surface temperatures are similar to those of main-sequence stars of the same mass, but they are significantly more luminous because their radii are larger. Their central temperatures are too low for hydrogen fusion. Colour and Temperature Based on the star's spectral type of K0IIIe, T Tauri's colour and type is orange to red T-Tauri star.

They are believed to be still in the process of gravitational contraction from their protostellar phase and have not yet arrived at the main sequence and begun to burn hydrogen. T Tauri stars (TTS) are a class of variable stars that are less than about ten million years old. [1] This class is named after the prototype, T Tauri, a young star in the Taurus star-forming region.They are found near molecular clouds and identified by their optical variability and strong chromospheric lines.

IR temperature difference is interpreted as cool or hot spots, or both, covering a significant part of the surface of T Tau N. The gravity derived for T Tau N $\log{g}=3.45 \pm 0.14$ is lower than the gravity of nearly every other star in a sample of 24 classical T Tauri stars in Taurus.

If playback doesn't begin shortly, try restarting your During the T Tauri phase of pre-stellar evolution, the protostar will actually fluctuate in brightness; however, on average, T Tauri stars are cooler and fainter than their final location in the HR diagram (0.7 Solar luminosities, 4,500 K). Theta Tauri (δ Tauri, förkortat Theta Tau, δ Tau) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Oxen och ingår i stjärnhopen Hyaderna.
