Historic Crown to Be Modified for Charles III Coronation

Britain's 17th-century St Edward's Crown, the centerpiece of the Crown Jewels, has been removed from display to be altered for the coronation of King Charles III, Buckingham Palace said on Saturday.

The solid gold crown, encrusted with rubies, amethysts, sapphires, garnet, topazes and tourmalines, will undergo "modification work" for Charles III's coronation at Westminster Abbey on May 6 next year, the palace said.

The crown is the centerpiece of the Crown Jewels, a large collection of royal regalia housed in the Tower of London that attracts more than a million visitors per year, AFP said.

It has a purple velvet cap with an ermine band, is just over 30 cm (one foot) tall and very heavy.

It was last worn by Queen Elizabeth II, at her coronation in 1953.

Charles III, 74, will be crowned along with his wife, Queen Consort Camilla.

The ceremony will be followed by a national holiday on May 8.

The crown was made for King Charles II in 1661 to replace a medieval crown though it date back to Edward the Confessor.

- 2,000 diamonds -
The original had been melted down by parliamentarians after the execution of Charles I.

For hundreds of years afterwards, the crown was only carried in coronation processions because it was too heavy to wear.

It was altered to make it lighter for the coronation of King George V in 1911 but still weighs 2.23 kilograms (nearly five pounds).

Charles III will only wear it at the moment he is crowned.

When he leaves Westminster Abbey, Charles will wear the more modern Imperial State Crown, also used for occasions such as the opening of parliament.

Set with over 2,000 diamonds, the Imperial State Crown was created in 1937 for the coronation of King George VI, the father of Elizabeth II.

The coronation traditionally takes place some months after a new sovereign has ascended to the throne, following a period of national and royal mourning, and intense preparation.

Charles immediately became king when his mother died on September 8. He also took over as head of state of 14 Commonwealth countries, including Australia, Canada and New Zealand.

Concerned about public perceptions, he has reportedly requested a less lavish ceremony than the festivities held for Elizabeth II in 1953.

The queen, who was 96, died at her Balmoral estate in Scotland after a year of declining health. She reigned for a record 70 years.

Scientists are tracking a large gas planet experiencing quite a quandary as it orbits extremely close to a young star - a predicament never previously observed.

This exoplanet, as planets beyond our solar system are called, orbits its star so tightly that it appears to trigger flares from the stellar surface - larger than any observed from the sun - reaching several million miles (km) into space that over time may strip much of this unlucky world's atmosphere, Reuters reported.

The phenomenon appears to be caused by the planet's interaction with the star's magnetic field, according to the researchers. And this star is a kind known to flare, especially when young.

"A young star of this type is an angry beast, especially if you're sitting as close up as this planet does," said Netherlands Institute for Radio Astronomy astrophysicist Ekaterina Ilin, lead author of the study published in the journal Nature.

The star, called HIP 67522, is slightly more massive than the sun and is located about 407 light-years from Earth in the constellation Centaurus. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

This star and planet, as well as a second smaller gas planet also detected in this planetary system, are practically newborns. Whereas the sun and our solar system's planets are roughly 4.5 billion years old, this star is about 17 million years old, with its planets slightly younger.

The planet, named HIP 67522 b, has a diameter almost the size of Jupiter, our solar system's largest planet, but with only 5% of Jupiter's mass. That makes it one of the puffiest exoplanets known, with a consistency reminiscent of cotton candy (candy floss).

It orbits five times closer to its star than our solar system's innermost planet Mercury orbits the sun, needing only seven days to complete an orbit.

A flare is an intense eruption of electromagnetic radiation emanating from the outermost part of a star's atmosphere, called the corona. So how does HIP 67522 b elicit huge flares from the star? As it orbits, it apparently interacts with the star's magnetic field - either through its own magnetic field or perhaps through the presence of conducting material such as iron in the planet's composition.

"We don't know for sure what the mechanism is. We think it is plausible that the planet moves within the star's magnetic field and whips up a wave that travels along magnetic field lines to the star. When the wave reaches the stellar corona, it triggers flares in large magnetic field loops that store energy, which is released by the wave," Ilin said.

"As it moves through the field like a boat on a lake, it creates waves in its wake," Ilin added. "The flares these waves trigger when they crash into the star are a new phenomenon. This is important because it had never been observed before, especially at the intensity detected."

The researchers believe it is a specific type of wave called an Alfvén wave, named for 20th century Swedish physicist and Nobel Prize laureate Hannes Alfvén, that propagates due to the interaction of magnetic fields.

The flares may heat up and inflate the planet's atmosphere, which is dominated by hydrogen and helium. Being lashed by these flares could blast away lighter elements from the atmosphere and reduce the planet's mass over perhaps hundreds of millions of years.

"At that time, it will have lost most if not all the light elements, and become what's called a sub-Neptune - a gas planet smaller than Neptune," Ilin said, referring to the smallest of our solar system's gas planets.

The researchers used observations by two space telescopes: NASA's TESS, short for Transiting Exoplanet Survey Satellite, and the European Space Agency's CHEOPS, short for CHaracterising ExOPlanet Satellite.

The plight of HIP 67522 b illustrates the many circumstances under which exoplanets exist.

"It is certainly no sheltered youth for this planet. But I am not sad about it. I enjoy diversity in all things nature, and what this planet will eventually become - perhaps a sub-Neptune rich in heavy elements that did not evaporate - is no less fascinating than what we observe today."
