Webin a binary system: Stellar wind accretion Compact stellar remnant (white dwarf, neutron star or black hole) gravitationally captures part of the stellar wind of a high mass star in the binary. Non-conservative mass transfer (not all the mass lost by one star is accreted by the other). Mass losing star is normally more massive than the accretor.
WebEvolved Binary February 5, 2024. Since late February 2024 we have been working on some low-level architectural changes in eXist-db to improve concurrency, scalability, and transaction isolation. In particular we have been focused on the lock implementation used in eXist-db and how those locks are applied (i.e., the locking policy). Web18 Jun 2024 · The Roche model (named for the nineteenth century French astronomer Édouard Roche) describes the gravitational potential of a close-binary system assuming that the two stars are well represented by synchronously-rotating point masses in a circular orbit [].While rather simplistic, this model is still a relatively good representation of many close …
Web1 Mar 2024 · (1) Background: We investigate the hypothesis that exoplanet engulfment can help explain the observed non-spherical planetary nebula population, as a complementary shaping mechanism to the binary hypothesis. The aim is to investigate the extent to which massive planets can explain the population of non-spherical planetary nebulae; (2) … WebUCO/Lick
