February 2024 Main astronomical analysis centre Armagh Observatory and Planetarium has performed a key function within the discovery of a singular signature of the method by which white dwarf stars cannibalise their planetary techniques.

The analysis was performed by a world staff of scientists utilizing the European Southern Observatory’s Chile-based Very Large Telescope (VLT).

Led by Armagh Observatory and Planetarium Astronomer, Stefano Bagnulo, the staff additionally includes John Landstreet, who’s Visiting Astronomer of the Armagh Observatory, in addition to Professor Emeritus of the Division of Physics and Astronomy at The University of Western Ontario (Canada).

The staff additionally consists of Jay Farihi from College Faculty London and Colin Folsom, who began his profession in Northern Eire as a PhD scholar of the Armagh Observatory and Queen’s College Belfast.

Titled “Discovery of Magnetically Guided Steel Accretion onto a Polluted White Dwarf”*, and revealed in The Astrophysical Journal Letters, the analysis paper outlines how a scar has been discovered printed on the floor of a magnetic white dwarf known as WD0816-310. The item is an Earth-sized remnant of a star within the neighbourhood of our photo voltaic system.

The noticed mark is a visual byproduct of the method by which white dwarfs ingest the encircling planets and asteroids which might be born with them.

The scar consists of a focus of metals that originate from a planetary fragment as giant as or probably bigger than Vesta, which is about 500 kilometres throughout, and is the second-largest asteroid in our Photo voltaic System.

The observations additionally present clues to how the star received its steel scar. Astronomers famous that the energy of the steel detection modifications because the star rotates, suggesting that the metals are focused on a selected space on the star’s floor.

Additionally they discovered that these modifications had been synchronised with fluctuations of the white dwarf’s magnetic subject and found that the steel scar is situated on one of many star’s magnetic poles.

This exhibits that the metals had been funnelled onto the star by its magnetic subject, creating the scar.***

Stefano Bagnulo, Astronomer at Armagh Observatory and Planetarium, says, “It’s well-known that some white dwarfs, that are slowly cooling embers of stars like our Solar, are cannibalising items of their planetary techniques. 

“Now now we have found that the white dwarf’s magnetic subject performs a key function on this course of, leading to a scar on its floor,” 

To succeed in these conclusions, the staff used the Very Giant Telescope’s FORS2 instrument.

Bagnulo continues, “ESO has the distinctive mixture of capabilities wanted to look at faint objects akin to white dwarfs, and sensitively measure stellar magnetic fields,”

Harnessing the facility of observations like these permits astronomers to disclose the majority composition of exoplanets, that are planets orbiting different stars outdoors the Photo voltaic System.

This artist’s impression exhibits the magnetic white dwarf WD 0816-310, the place astronomers have discovered a scar imprinted on its floor because of having ingested planetary particles. When objects like planets or asteroids strategy the white dwarf they get disrupted, forming a particles disc across the useless star. A few of this materials may be devoured by the dwarf, leaving traces of sure chemical parts on its floor.  Utilizing ESO’s Very Giant Telescope, astronomers discovered that the signature of those chemical parts modified periodically because the star rotated, as did the magnetic subject. This means that the magnetic fields funneled these parts onto the star, concentrating them on the magnetic poles and forming the scar seen right here. Credit score: ESO/L. Calçada

This examine additionally exhibits how planetary techniques can stay dynamically energetic, even after their ‘demise’.

John Landstreet, co-author of the analysis paper, is member of the team that discovered the first magnetic white dwarf, again in 1970, and remains to be very energetic in astronomical analysis.

He provides: “Surprisingly, the fabric was not evenly combined over the floor of the star, as predicted by idea. 

“As a substitute, this scar is a concentrated patch of planetary materials, held in place by the identical magnetic subject that has guided the infalling fragments. Nothing like this has been seen earlier than.”
