Thermally-induced α→β phase transformation interweaving with abnormal α grain growth in hot extruded TNM alloy

open access: yesJournal of Materials Research and Technology, 2021
The microstructural and crystallographic features of the β phase in TNM alloy during the hot extrusion at 1290 °C and the subsequent cooling process were investigated. Except the original grain boundary β phase, two categories of β particles, along grain

Comparison of Low-Mass and High-Mass Star Formation

open access: yes, 2015
I review theoretical models of star formation and how they apply across the stellar mass spectrum. Several distinct theories are under active study for massive star formation, especially Turbulent Core Accretion, Competitive Accretion and Protostellar ...

On Low Mass AGB Stars [PDF]

open access: yesSymposium - International Astronomical Union, 1991
Recent results on low mass AGB stars are presented. Observed amounts of AGB mass loss imply that thermal pulses will only be encountered for stars of initial mass less than about 4M⊙ for Pop I and 3 M⊙ for Pop II. Mc – L, Me – τif, and Mc – Tb relations are summarized.

Accretion onto Planetary Mass Companions of Low-Mass Young Stars [PDF]

open access: yes, 2014
Measurements of accretion rates onto planetary mass objects may distinguish between different planet formation mechanisms, which predict different accretion histories.

Association between total protein intake and low muscle mass in Korean adults

open access: yesBMC Geriatrics, 2022
Background Adults with low muscle mass have a poor prognosis. Studies that examined the association between total protein intake and low muscle mass among adults are limited.

Nearby Low-Mass Hypervelocity Stars

open access: yes, 2014
Hypervelocity stars are those that have speeds exceeding the escape speed and are hence unbound from the Milky Way. We investigate a sample of low-mass hypervelocity candidates obtained using data from the high-precision SDSS Stripe 82 catalogue, which ...

Five new very low mass binaries [PDF]

open access: yes, 2006
We report the discovery of companions to 5 nearby late M dwarfs (>M5), LHS1901, LHS4009, LHS6167, LP869-26 and WT460, and we confirm that the recently discovered mid-T brown dwarf companion to SCR1845-6357 is physically bound to that star.
