The discovery, part of Yal\u00e7\u0131nkaya\u2019s Ph.D. research at Ankara University\u2019s Institute of Science, was published in the prestigious journal Astronomy &amp; Astrophysics.<\/p>\n<p>Supported by the T\u00dcBITAK 2214-International Research Fellowship Programme for Ph.D. Students, Yal\u00e7\u0131nkaya conducted part of his work at the University of Liege in Belgium, while continuing his observations in T\u00fcrkiye. Collaborating with a global team that includes Nobel laureates, he applied the transit method \u2013 one of astronomy\u2019s primary techniques for discovering exoplanets \u2013 to study several stars and uncover these distant worlds.<\/p>\n<p>Using telescopes at Ankara University\u2019s Kreiken Observatory (AUKR) and the Turkish National Observatory (TUG), as well as nearly 20 instruments around the world \u2013 from Chile and Mexico to the Canary Islands \u2013 the team confirmed four exoplanets: two orbiting the small, cool star TOI-5799 and one each around TOI-1743 and TOI-6223.<\/p>\n<p>Key discoveries<\/p>\n<p>Each exoplanet tells its own story. TOI-6223b is a hot Neptune, comparable in size to Neptune in our solar system, yet orbiting so close to its star that it sizzles under intense heat. Its atmosphere remains a mystery, awaiting future observations.<\/p>\n<p>TOI-1743b is a super-Earth roughly 70% larger than Earth. It orbits extremely close to its star, completing a full revolution in just four days. The intense radiation it receives likely stripped away its atmosphere long ago, leaving a rocky, scorched world.<\/p>\n<p>The TOI-5799 system is especially exciting. This system hosts two super-Earths, TOI-5799b and TOI-5799c, each about 70% larger than Earth. TOI-5799b orbits its star in just four days, making it far too hot to support life. In contrast, TOI-5799c occupies the star\u2019s habitable zone, completing a 14-day orbit. Its estimated surface temperature is around 63 degrees Celsius (145.4 degrees farenhiet), though actual conditions could differ depending on its unknown atmosphere.<\/p>\n<p>                    <a data-fancybox=\"gallery\" href=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2025\/11\/410760.jpg\" data-caption=\"Sel\u00e7uk Yal\u00e7\u0131nkaya (L), a Ph.D student at Ankara University\u2019s Institute of Science, and professor \u00d6zg\u00fcr Ba\u015ft\u00fcrk, a faculty member of Ankara University\u2019s Faculty of Science, Ankara, T\u00fcrkiye, Nov. 5, 2025.

(AA Photo) <\/p>\n<p>Yal\u00e7\u0131nkaya emphasizes that TOI-5799c is particularly promising for future study. Its location on the inner edge of the habitable zone, combined with the potential for an atmosphere, makes it one of the few rocky exoplanets where scientists could search for biosignatures \u2013 subtle signs of life. This position also makes TOI-5799c an ideal candidate for observation by the James Webb Space Telescope (JWST).<\/p>\n<p>How they found them<\/p>\n<p>The journey to these discoveries began with data from the TESS space telescope, which scans the sky for transit signals \u2013 tiny dips in starlight caused when a planet crosses in front of its host star. Yal\u00e7\u0131nkaya explains that after identifying these initial signals, the team confirms their origin using ground-based telescopes, including the 80 cm telescopes at AUKR.<\/p>\n<p>\u201cBy observing from multiple locations on Earth, we can determine whether a signal genuinely comes from the target star or from nearby stars,\u201d Yal\u00e7\u0131nkaya says. \u201cOnce confirmed, we perform additional experiments to understand the nature of the signal and verify the planet\u2019s presence.\u201d<\/p>\n<p>This collaborative, international approach, combining telescopes from around the world, was essential to the success of the project.<\/p>\n<p>Looking ahead<\/p>\n<p>Professor \u00d6zg\u00fcr Ba\u015ft\u00fcrk, Yal\u00e7\u0131nkaya\u2019s thesis adviser, highlights the potential of TOI-5799c. \u201cThe next step is to study its atmosphere. Using JWST, we can observe its transits and investigate whether it has an atmosphere, and if so, whether it contains features that could indicate life. This planet is among a rare few rocky worlds where this is even possible.\u201d<\/p>\n<p>Ba\u015ft\u00fcrk emphasizes that discovering a planet in the habitable zone does not mean life exists there. \u201cBut TOI-5799c is a prime candidate. Its location, size, and potential for an atmosphere make it one of the most exciting exoplanets for future research.\u201d<\/p>\n<p>The discoveries not only add four new worlds to humanity\u2019s cosmic map but also demonstrate the power of international collaboration and advanced observational techniques in the search for potentially habitable planets beyond our solar system.<\/p>\n<p>                    <img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2025\/09\/JN9LXf.png\" alt=\"\"\/><\/p>\n<p>&#13;<br \/>\n                    The Daily Sabah Newsletter&#13;\n                <\/p>\n<p>&#13;<br \/>\n                    Keep up to date with what\u2019s happening in Turkey,&#13;<br \/>\n                    it\u2019s region and the world.&#13;\n                <\/p>\n<p>&#13;<br \/>\n                    &#13;<br \/>\n                    SIGN ME UP&#13;\n                <\/p>\n<p>&#13;<br \/>\n                    You can unsubscribe at any time.
