The newly deployed Chippos Space Telescope has completed its first observations Explanet, revealing some interesting new details about the ultra-hot Jupiter known as WASP-189B.
Hot Jupiter is a Jupiter-like exoplanet located near their host stars, hence its name. Basically ultra-hot goopers are the same thing, but, As you have done Probably guessed, they’re even hotter. Back in 2018, astronomers use the ground-based WASP-SOth Telescope in South Africa Detected Ultra-Hot Jupiter Dub WASP-189B, U.S.Not like anything seen before.
Two years later, using the brand–spanking-New Feature Exoplanet Satellite (CHOPS) Space Telescope, Astronomers have seen this space wonder with new eyes, improving what we know about this unusual exoplanet, while at the same time giving this European space telescope the potential began to create scientific knowledge. Observations this past April.
Indeed, chips, when compared to ground-based telescopes, are “easily more accurate,” explained Monica Lendl, an astronomer at the University of Geneva and lead author of the new study, via email. “Since CHEPS is observed from space, it does not need to be seen in the Earth’s atmosphere. And so the light is not disturbed by the turbulence of the air. “
The EOPS, in collaboration with the European Space Agency and the Swiss Space Agency, is designed to detect and observe the Exoplanet simply by dipping into the brightness of the star – a possible sign of the Exoplanet going forward (i.e. the transport method). . CHIPPS will also study previously discovered exoplanets, such as the WASP-189b here.

“The chaps have a unique ‘follow-up’ role in studying such exoplanets,” Kate Prayasi, ESA’s CHEPS project scientist and co-author of the new study, said in a press release. “It will detect the transitions of the planets discovered from Earth, and where possible, will more accurately measure the size of the planets known to move their host stars.”
A new one Paper The description of the first formal formal investigation of the space telescope has been published on astronomy and astrophysics.
WASP-189b 322 light-locatedYears away in Libra in the Southern Hemisphere. This ultra-hot Jupiter A-type star is in tight orbit around HD 133112, which Glow in blue. At just 7.7 million miles (.5. Million million km) from its host star, the exoplanet needs only 4.7 days to complete full orbit. This cozy adjustment – give a distance of about 5% Sun from Earth – WASP-189B is very hot, new chips data corrects previous estimates.
The temperature of WASP-189b is really harsh, Because this gas is giant Absolutely brilliant, which creates conflicting data between itself and its host star. To get around this, Lendl and his comrades wait for the spy, in which the planets pass through our view behind their host stars (as opposed to the type of transition method). This allowed the scientists to accurately discern the luminosity of the exoplanet, which in turn allowed them to take its temperature.
“WASP-189b is one of the hottest gas giants known to exist,” Lendl said. “With EOPS, we are able to determine the brightness of the days of the planets and find that the light emitted by them corresponds to a planet with a temperature of about 3,200 degrees Celsius. [5,800 degrees Fahrenheit]”
It’s intense; Our sun is only 2,000 degrees Celsius (3,630 degrees F) hotter than this fiery planet. And in fact, the WASP-189B is actually warmer than some red dwarf stars, which cook well below temperatures below 3,000 degrees C (5,430 degrees F). There are possibilities of any life on this planet Basically zero, like Iris also converts to gas from this extreme.
A few planets are known as this hot. WASP-189B is also a brilliant hot guru known to scientists.
Researchers Purified the mass of the exoplanet, finding that it is about twice as heavy as Jupiter. They also updated the diameter of the WASP-189b, Find that it is 1.6 Jupiter’s width, Or 139, 000 miles (224), 000 km), which is slightly larger than the previous calculations.
Scientists have also noted that the star, HD 133112, Not perfectly round – it’s really a kind of squid, hovering at the equator, Where it is significantly cooler than the polar regions. Star fast SpinING And as a result, centralized tidal forces are contributing Strange shape, note the authors of the study.
Interestingly, WASP-189B is in a trend orbit, which means that it is not connected to the star’s equatorial plane. Indeed, it is Really Incorrectly connected, zoom above the star’s polar regions. This is an important observation, as it means that the exoplanet potential formed FAExit And then slowly shifted inward over time. This track happened towards the host star Either way Due to the gravitational influence of other planets of the same system Or Researchers speculate on the influence of the second star.
With the completion of WASP-189B observations, Chapops will now turn his attention to hundreds of other well-known exoplanets and their host stars, to further their mass, size, and orbit. As this inaugural investigation makes clear, we can expect a lot more from this exciting new space telescope.
