1993-11-01 · Recent photometric observations of T Tauri stars at submillimeter and millimeter wavelength regions by Beckwith and Sargent (1991, Astrophys, J. 381, 250-258) have revealed that power law indices β of frequency dependence of particle opacities in circumstellar disks around T Tauri stars are 0-1; and these values of β are lower than the interstellar value of β ≅ 2.

The bigger a star is, the shorter its lifespan is.

It was unusual for a T-Tauri star system to have a planet in the class M range. Small, extremely unstable wormholes are a phenomenon sometimes encountered near T-Tauri systems – in the century between 2267 and 2367, thirty-nine had been mapped.

The general belief is that T Tauri stars are newly forming stars in the galaxy and may be growing in size through accretion. Brightness changes detected in these stars are not due to evolutionary effects, per se, but may be due to such processes as instabilities in the disk, violent activity in the atmosphere of the star, and may also be due in

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. 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 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 therefore represent an intermediate stage between real protostars (e.g. YY Orionis stars) and low-mass main sequence (hydrogen burning) stars like the Sun. The nearest T Tauri stars to us are in the Taurus and ρ-Ophiuchus molecular clouds, both about 400 light years away. 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.

The nearest T Tauri stars to us are in the Taurus and ρ-Ophiuchus molecular clouds, both about 400 light years away. The prototypical T Tauri star – T Tauri itself – is part of a close binary system with a smaller, fainter companion. This is visible … Much of the work on disk timescales has been done on T Tauri stars, which are < 2 solar mass pre-main-sequence stars. They typically are < 5 Ma in age, accrete at ~ 10 –7 –10 –9 solar masses per year, and have disk masses of about 5 × 10 –3 solar masses and median disk/star mass ratios of 0.5% ( Mamajek, 2009 ), that is, about half that estimated for our own minimum mass solar nebula. 195 rows Using NASA Infrared Telescope Facility SpeX data from 0.8 to 4.5 μm, we determine self-consistently the stellar properties and excess emission above the photosphere for a sample of classical T A T-Tauri type was a type of star.
