Core overshoot constrained by the absence of a solar convective core and some solar-like stars

Yunnan Observatories of the Chinese Academy of Sciences and Aarhus University researchers have found a constraint of the convective core overshoot in low-mass stars and a correlation between the strength of overshoot and the stellar mass. The study was published in Monthly Notices of the...

Scientists iron out the interiors of exoplanets

Lawrence Livermore National Laboratory scientists have used lasers to determine the high-pressure melting curve and structural properties of pure iron up to 1,000 GPa. This is three times the pressure of Earth's inner core. It is also four times greater pressure than any previous...

Scientists discover cool ‘hotspots’ under Earth’s crust

A new study found out that hotspots that created volcanic islands like Iceland may often prove surprisingly cool. Scientists said, hotspots may not originate from giant plumes of very hot rock welling up from near Earth's core. Volcanoes are found near the borders of tectonic plates. These...
