An independent German commission is recommending the restitution of a painting by Wassily Kandinsky currently owned by the Bavarian state bank to the heirs of a Jewish family that the artwork originally belonged to

A white dwarf star is undergoing the process of turning into a “cosmic diamond” as it begins to crystalise. The lullaby “Twinkle Twinkle Little Star” talks about stars in the sky looking like diamonds, but for one specific type of star, that observation is truer than for others. Astronomers have observed that when a specific type of dead star starts to cool, it begins to crystalise and harden. An international team of astronomers, led by Alexander Venner of the University of Southern Queensland in Australia, have explained in a new paper Monthly Notices of the Royal Astronomical Society how a white dwarf star around 104 light-years away is doing just that. They noticed that the star, composed primarily of carbon and metallic oxygen, has a temperature-mass profile that suggests its centre is hardening into a dense “cosmic diamond” made of crystallised carbon and oxygen. The study explained: "In this work we present the discovery of a new Sirius-like quadruple system at 32 parsecs distance, composed of a crystallizing white dwarf companion to the previously known triple HD 190412.” Sign up to our free Indy100 weekly newsletter It continued: “By virtue of its association with these main sequence companions, this is the first crystallizing white dwarf whose total age can be externally constrained, a fact that we make use of by attempting to empirically measure a cooling delay caused by core crystallization in the white dwarf.” All stars eventually die out when they run out of energy. Of those that have a mass of less than around eight times that of the Sun, the vast majority will form a white dwarf star. The matter of a white dwarf star is highly compressed and as they gradually cool, they evolve into a black dwarf star when they lose heat and crystalise. Scientists’ calculations estimate the process takes around a quadrillion years (one million billion years) to complete, though the signs that the process is occurring can be identified by experts.

Liverpool full-back Calvin Ramsay is set to join Preston on loan for next season. The 19-year-old managed just 93 minutes of football – across two matches in the Carabao Cup and Champions League in November – due to a back problem and then a knee injury which prematurely ended his maiden campaign. Ramsay underwent surgery in February and is in need of regular first-team football which is why, the PA news agency understands, he has been allowed to go out on loan to the Championship side. The Scotland international arrived at Anfield last summer from Aberdeen for an initial £4million.
