La stella più veloce della Via Lattea orbita attorno al nostro buco nero supermassiccio a una distanza talmente ravvicinata da percepirne la rotazione

Gli astronomi hanno scoperto la stella più veloce finora conosciuta nella […]

Questa immagine mostra la traiettoria della stella S301 attorno a Sagittarius A*, il buco nero supermassiccio al centro della nostra galassia. I rombi indicano le misurazioni effettuate con lo strumento GRAVITY presso l’Interferometro del Very Large Telescope (VLTI) dell’ESO. Come riferimento è riportata la dimensione dell’orbita di Nettuno. S301 orbita attorno a Sagittarius A* ogni 8 anni. Nel farlo, la sua orbita ruota formando una rosetta. Questo effetto, noto come precessione di Schwarzschild, era già stato misurato attorno a Sagittarius A* e si verifica indipendentemente dal fatto che il buco nero ruoti o meno. Tuttavia, se il buco nero ruota, entra in gioco un effetto diverso. Mentre ruota, il buco nero trascina e distorce lo spazio-tempo attorno a sé, un fenomeno noto come effetto Lense-Thirring. La stella S301 si avvicina talmente tanto al buco nero da poter essere influenzata da questo fenomeno. Lo spazio-tempo contorto attorno al buco nero modificherebbe leggermente l’orbita di S301 ad ogni passaggio ravvicinato. Dopo diversi anni, la differenza tra le orbite previste per un buco nero non rotante e uno rotante sarebbe minima, pari all’incirca alle dimensioni dell’orbita terrestre attorno al Sole, ma sufficientemente grande da poter essere misurata con il VLTI e l’Extremely Large Telescope (ELT) dell’ESO, attualmente in fase di costruzione. Questa sequenza di immagini, ottenute con lo strumento GRAVITY installato sul Very Large Telescope Interferometer (VLTI) dell’ESO, mostra diverse stelle in orbita attorno a Sagittarius A*, il buco nero supermassiccio situato al centro della nostra galassia. Una di queste stelle, denominata S301, è stata recentemente scoperta mentre passava molto più vicino al buco nero rispetto a qualsiasi altra stella conosciuta. S301 orbita attorno a Sagittarius A* ogni 8,7 anni. Nel punto di massima vicinanza — a una distanza simile a quella tra il Sole e Saturno — la stella si muove a oltre l’8% della velocità della luce. Per confronto, nell’immagine è indicata anche la dimensione dell’orbita di Nettuno. S301 passa così vicino a Sagittarius A* che la sua orbita potrebbe essere influenzata dalla rotazione del buco nero, che attorciglia lo spaziotempo nelle sue vicinanze. L’effetto è piccolo, ma potrebbe essere misurato potenzialmente nei prossimi anni con il VLTI e con l’Extremely Large Telescope (ELT) dell’ESO, attualmente in costruzione. L’orbita di S301 è rappresentata qui mediante una curva ellittica. In ogni fotogramma, la curva continua mostra il percorso che la stella ha già compiuto fino a quel momento, mentre la curva tratteggiata indica il percorso che seguirà successivamente. Questa sequenza di immagini, acquisita con lo strumento GRAVITY presso l’Interferometro del Very Large Telescope (VLTI) dell’ESO, mostra diverse stelle in orbita attorno a Sagittarius A*, il buco nero supermassiccio al centro della nostra galassia. Queste stelle sono note collettivamente come stelle di tipo S. Le frecce nelle immagini indicano il loro moto osservato attorno al buco nero. Recentemente è stato scoperto che una delle stelle, S301, passa molto più vicino al buco nero rispetto alle altre stelle S. La sua orbita è qui rappresentata da una curva ellittica. In ogni fotogramma, la curva continua mostra il percorso che la stella ha già completato fino a quel momento, mentre quella tratteggiata indica il percorso che seguirà in seguito.

The fastest known star in the Milky Way orbits our galaxy's central black hole at 25,000 km/s, 8% of the speed of light. Astronomers just found it. And it is the key to a measurement nobody has ever made.

Milky Way's fastest star orbits a black hole so close, it feels its spin
Astronomers have discovered the fastest known star in our galaxy, the Milky Way, orbiting the black hole at its centre. The star, named S301, was detected with the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) and reaches speeds of 25 000 km/s as it travels aro

S301 was detected using the VLTI interferometer and the GRAVITY instrument at ESO’s Paranal Observatory.

It is extremely faint — two billion times fainter than Betelgeuse.

The observations cover the years from 2017 to 2025.

Hallan la estrella más rápida de la Vía Láctea: viaja a 25.000 km/s, más del 8% de la velocidad de la luz y permitirá poner a prueba la teoría de la relatividad de Einstein
Un equipo de astrónomos ha descubierto la estrella más rápida conocida de la Vía Láctea, que alcanza velocidades de 25.000 kilómetros por segundo (km/s) a medida que gira alrededor del agujero negro que hay en su centro, el Sagitario A*, de cuatro millones de masas solares. La estrella, llamada S301, fue detectada con el VLTI, es decir, el Interferómetro del VLT (Very Large Telescope) del Observatorio Europeo Austral (ESO por sus siglas en inglés), que ha informado de la revelación este miércoles.

ICYMI Our VLTI has found a star that’s breaking records!

➡️ It’s the fastest star known in our galaxy
➡️ It comes closer to the #MilkyWay ’s supermassive #BlackHole than any other star found before.

This makes it the first star that could allow us to measure the black hole’s spin.
