Their spectra show a higher lithium abundance than the Sun and other main- sequence stars because lithium is destroyed at temperatures above 2,500,000 K. Question 10.

In the ultraviolet the continuum seems to be well explained by the sum of the stellar black body emission plus a hydrogenic component with temperature in the Stars form inside relatively dense concentrations of interstellar gas and dust known as molecular clouds. These regions are extremely cold (temperature about 10 to 20K, just above absolute zero). At these temperatures, gases become molecular meaning that atoms 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). T Tauri Star: A T Tauri star is a stage in a star’s formation and evolution right before it becomes a main-sequence star.. This phase occurs at the end of the protostar phase when the gravitational pressure holding the star together is the source of all its energy. DL Tauri Colour and Temperature Based on the star's spectral type of K7Ve C , DL Tauri's colour and type is orange to red T-Tauri star. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 3,500 and 5,000K based on the notes from Harvard University .

They are more luminous than main sequence stars of similar spectral types , and they have a high lithium abundance, which is a pointer to their extreme youth, as lithium is rapidly destroyed in stellar interiors. 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 (M ☉) in the pre-main-sequence phase of stellar evolution. This star is about 10 million years old and is already showing signs of evolution both with the apparent existence of planets (presumably newly formed) and also with a probable reduction in accretion rate compared to more rapidly accreting younger T Tauri stars of 1 million years of age (Muzerolle et al. 2000). temperature T sub (R wall ∝ T −2.085 sub), which is con-sistent with simplified expressions commonly used. The range of dust sublimation temperature in terms of gas density is between 10−18 and 10−4 g cm−3 and it is given for different grain species by Pollack et al.

Class T dwarfs are brown dwarfs with a surface temperature between 700 and 1,300 K. They are sometimes known as Methane Dwarfs due to the prominence of methane in their composition. They are on the borderline between what might be considered a very large gas giant planet and a star. Class T star systems tend to contain many icy bodies.
