The chaotic cores of Perseus protostars
The formation of a star has a simple tale. A region of interstellar gas collapses under its own weight, eventually forming a dense protostar surrounded by a disk of gas and dust. The protostar and the disk rotate in the same plane, and often jets of.....»»

Unraveling positional and structural errors in numerical weather forecast models
Due to the chaotic nature of the atmosphere, weather forecasts, even with ever improving numerical weather prediction models, eventually lose their accuracy. Meteorologists have a strong desire to better understand this process as they try to trace f.....»»
AMD Ryzen 6000 APUs rumored to offer 50% more graphics power
AMD's Ryzen 6000 APUs will reportedly come with up to 12 RDNA 2 graphics cores, bolstering the performance of AMD's integrated graphics......»»
High-mass stars are formed not from dust disk but from debris
A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic m.....»»
FAST detects 3D spin-velocity alignment in a pulsar
Pulsars—another name for fast-spinning neutron stars—originate from the imploded cores of massive dying stars through supernova explosion......»»
Intel Core i7-11370H Review: Quad-Cores Aren"t Enough in 2021
The Core i7-11370H is part of the Tiger Lake H35 line-up that bridges the gap between the UP3 series for ultraportables, and the 45W H-series chips used for work and gaming machines. Unfortunately, it fails at it......»»
A violent delidding reveals that Intel"s Sapphire Rapids CPUs could have up to 80 cores
Eighty cores is twice the amount you can currently purchase from Intel for up to $8,099, though it’s only a third more than what AMD could sell you for $7,890. But Intel’s flashiest Xeons and AMD’s shiniest Epycs are more similar than you'd ima.....»»
Ryzen rumors: Zen 5 to use Alder Lake-style hybrid design, Zen 3+ canceled due to chip shortage
Intel's Alder Lake chips, set to debut in the second half of this year, will bring the combination of larger high-performance cores and smaller high-efficiency cores to desktop x86 PCs. 2022's Raptor Lake, which also uses the LGA 1700 socket, will fe.....»»
A superluminous supernova from a massive progenitor star
Stars greater than about eight solar-masses end their lives spectacularly as supernovae. These single-star supernovae are called core collapse supernovae because their dense cores, composed primarily of iron at this late stage of their lives, are no.....»»
Surprise twist suggests stars grow competitively
A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas cores, which may evolve into stars. Counterintuitively, this means that the amount of gas a core accretes as it develops,.....»»
Machine-learning methods lead to discovery of rare "quadruply imaged quasars"
With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic "lens" and split into four similar images. Quasars are extremely luminous cores of distant galaxi.....»»

Some Dead Stars May Harbor Enough Uranium To Set Off a Thermonuclear Bomb
sciencehabit shares a report from Science Magazine: A thermonuclear bomb might be ticking deep in the cores of some dead stars. A new theoretical study traces out how certain stellar corpses known as white dwarfs could accumulate a critical mass of u.....»»
Not so fast, supernova: Highest-energy cosmic rays detected in star clusters
For decades, researchers assumed the cosmic rays that regularly bombard Earth from the far reaches of the galaxy are born when stars go supernova—when they grow too massive to support the fusion occurring at their cores and explode......»»
