Hayashi track. From Wikipedia, the free encyclopedia. Stellar evolution tracks (blue lines) for the pre-main-sequence. The nearly vertical curves are Hayashi tracks. Low-mass stars have nearly vertical evolution tracks until they arrive on the main sequence. For more-massive stars, the Hayashi track bends to the left into the Henyey track.

The Hayashi track refers to a linear path on the Hertzsprung-Russell diagram taken by a protostar, an interstellar cloud of gas evolving into a star. The gas contracts and heats by gravitational collapse into a dense core and glows as a black body without any nuclear reactions. Hydrostatic forces give the cloud its shape and size, as gas ...

Stars less than are fully convective even on the main sequence, but their opacity begins to ...Henyey track.

Hayashi Track: The Hayashi track is a luminosity-temperature relationship obeyed by infant stars of less than 3 Solar Masses in the pre-main-sequence phase (PMS phase) of stellar evolution. It is named after Japanese astro physicist Chushiro Hayashi.

The pre main sequence star (not protostar) is powered by the release of gravitational potential energy caused by its contraction . If the star is getting smaller at constant effective temperature, then of course it's luminosity ($\propto R^2 T^4$) decreases. One such approach is “racetrack” memory (RM) ( 1 ), in which magnetic domains are used to store information in tall columns of magnetic material arranged perpendicularly on the surface of a silicon wafer ( Fig. 1 ).

The Hayashi track is a luminosity–temperature relationship obeyed by infant stars of less than 3 M☉ in the pre-main-sequence phase (PMS phase) of stellar evolution. It is named after Japanese astrophysicist Chushiro Hayashi. On the Hertzsprung–Russell diagram, which plots luminosity against temperature, the track is a nearly vertical curve.Here we derive new scaling relations based on a relation for stars on the Hayashi track ($\sqrt{T_{\rm eff}} \sim g^pR^q$) to determine the masses and metallicities of red giant branch stars in open clusters NGC 6791 and NGC 6819 from the global oscillation parameters $\Delta\nu$ (the large frequency separation) and $\nu_{\rm max}$ (frequency ...The Sun took 30 million years to evolve from a collapsing cloud core to a star, with 10 million of those years spent on its Hayashi track. It will spend a total of 10 billion years on the main sequence. Suppose the Sun's main-sequence lifetime was compressed into a single day. a. How long would the total collapse phase last? b.At the lowest accretion rates stars descend Hayashi tracks to the ZAMS, and then evolve along it because τ Ṁ ⪡ τ N. Above 0.3 M ⊙, stars develop a radiative core on and just above the main sequence. This causes a contracting pre-main-sequence star to leave its Hayashi track and move to higher temperature before reaching the ZAMS.This was done using 0.8 to 4.4 M_⊙ stellar models at stages ranging from the end of the Hayashi track up to the Zero-Age Main-Sequence (ZAMS). This research concludes that, for intermediate-mass stars (M > 1.3 M_⊙), diagrams comparing the effective temperature (T_eff) against the small separation can provide an alternative to Christensen-Dalsgaard …
