Superbursts are rare day-long Type I X-ray bursts due to carbon flashes on accreting neutron stars in low-mass X-ray binaries. They heat the neutron star envelope such that the burning of accreted hydrogen and helium becomes stable, and the common shorter X-ray bursts are quenched. Short ...
“If the magnetic field is stronger on one side, it could be limiting convection [bubbling in the helium layer],” Caiazzo said. “On the other side, convection could be winning out and so the hydrogen layer has been lost.” The findings are published in the journal Nature....
Hydrogen-poor and helium-rich stars are easy to produce in interacting binaries. Thus they should be found among Population I binaries, in which a large-scale mass transfer has occurred between the...doi:10.1007/978-94-009-4744-3_28Mirek J. Plavec...

Other elements were created much later when hydrogen and helium fused inside stars. Answered by Alexandra Cheung for Brain Dump in How It Works issue 103 To feature in our Brain Dump section, send us your questions to howitworks@futurenet.com or message us on Facebook or Twitter For more...
Progress is hampered by our inability to distinguish between red giants burning helium in the core and those still only burning hydrogen in a shell. Asteroseismology offers a way forward, being a powerful tool for probing the internal structures of stars using their natural oscillation frequencies....
