Destiny 2 [b] is a free-to-play online first-person shooter video game developed by Bungie.It was originally released as a pay to play game in 2017 for PlayStation 4, Xbox One, and Windows.
For stars with a degenerate helium core, there is a limit to this growth in size and luminosity, known as the tip of the red-giant branch, where the core reaches sufficient temperature to begin fusion. All stars that reach this point have an identical helium core mass of almost 0.5 M ☉, and very similar stellar luminosity and temperature ...
The DAO bug. On June 17, 2016, the DAO was subjected to an attack exploiting a combination of vulnerabilities, including the one concerning recursive calls, that resulted in the transfer of 3.6 million Ether – around a third of the 11.5 million Ether that had been committed to The DAO – valued at the time at around $50M.

If the user has enabled it, the system will also write an entry to the system event log. The log entry contains information about the bug check (including the bug check code and its parameters) as well as a link that will report the bug and provide the user with prescriptive suggestions if the cause of the check is definitive and well-known.
In the helium cores of stars in the 0.6 to 2.0 solar mass range, which are largely supported by electron degeneracy pressure, helium fusion will ignite on a timescale of days in a helium flash. In the nondegenerate cores of more massive stars, the ignition of helium fusion occurs relatively slowly with no flash. [ 14 ]
A helium flash is a very brief thermal runaway nuclear fusion of large quantities of helium into carbon through the triple-alpha process in the core of low-mass stars (between 0.8 solar masses (M ☉) and 2.0 M ☉ [1]) during their red giant phase. The Sun is predicted to experience a flash 1.2 billion years after it leaves the main sequence.
Also, dedicated section Isotopes of helium § Helium-2 (diproton) has more sources. - DePiep ( talk ) 17:57, 9 October 2021 (UTC) [ reply ] But NUBASE2020 does include other isotopes with half-lives much shorter than 100 ns 4 H = 139 ys = 139 x 10 -24 s, 4 Li = 91 ys, 5 H = 86 ys, 5 He = 602 ys, 5 Li = 370 ys, etc. Dirac66 ( talk ) 18:55, 9 ...
When distant stars at the TRGB are measured in the I-band (in the infrared), their luminosity is somewhat insensitive to their composition of elements heavier than helium (metallicity) or their mass; they are a standard candle with an I-band absolute magnitude of –4.0±0.1. [3] This makes the technique especially useful as a distance indicator.
