The Heat of Proximity
One of the most fascinating aspects of TOI 733b is its incredibly close proximity to its host star. Positioned at a distance of a mere 0.0618 astronomical units (AU), this exoplanet experiences intense heat from its star. This proximity raises a compelling possibility: TOI 733b's atmosphere could be evaporating due to the relentless stellar radiation, transforming it into a barren, rocky world in a relatively short span of time.
A Cosmic Conundrum
But what makes TOI-733b truly remarkable is its potential to help scientists solve a profound mystery in exoplanet research—the puzzling gap in the exoplanet size distribution. Why are there so few worlds with radii between 1.5 and 2 times that of Earth? This gap has confounded astronomers for years, and TOI 733b might offer a clue.
Patterns in Exoplanet Discovery
Over the past few decades, we've witnessed an explosion in exoplanet discoveries, with over 5,300 confirmed exoplanets and countless more candidates. This data has allowed us to identify patterns in the exoplanet population. Two primary detection methods, transits and radial velocity measurements, have their limitations, often favoring larger planets in close orbits. However, some patterns can't be solely attributed to our detection methods.
The Small Planet Radius Valley
One of the most intriguing enigmas is the small planet radius valley. Few exoplanets exist between the categories of super-Earths (up to 1.5 Earth radii) and mini-Neptunes (over 2 Earth radii). Recent evidence suggests that mini-Neptunes may be shrinking, shedding their atmospheres under the intense heat of their stars, leaving behind smaller, naked cores.
Cracking the Mystery
TOI 733b lies within the radius valley and presents a golden opportunity to study the process that might be causing this intriguing gap in exoplanet sizes. By identifying more planets undergoing this transformation, astronomers can analyze them and gain insights into the underlying mechanisms at play.
A Multifaceted Approach
Astronomers led by Iskra Georgieva from Chalmers University of Technology in Sweden discovered TOI 733b using data from NASA's TESS telescope and the HARPS spectrograph at the ESO La Silla 3.6-meter telescope. Transit data unveiled the exoplanet's orbital period and radius, while radial velocity measurements provided its mass. These values were used to calculate its density and infer its composition.
A Stellar Discovery
This exoplanet didn't simply materialize out of thin air. It was discovered as part of the KESPRINT follow-up program, utilizing the HARPS spectrograph. The Kepler Space Telescope provided invaluable photometric data from sectors 9 and 36, enabling astronomers to deduce its orbital period and radius.
A Matter of Composition
One of the key distinctions of TOI-733 b lies in its composition. A multi-dimensional Gaussian process model analysis revealed a semi-amplitude of 2.23 ± 0.26 m s^-1 for its radial velocity, corresponding to a planet mass of 5.72 M⊕. What sets it apart is its placement on the mass-radius diagram, marking the transition between rocky and volatile-rich planets with H/He-dominated envelopes. In essence, it's a cosmic chameleon, straddling the line between different planetary categories.
A Watery Enigma
Peering beneath its surface, TOI 733b reveals even more secrets. Detailed calculations of its interior and atmosphere suggest the presence of a volatile-enriched, likely secondary outer envelope. This tantalizing clue hints at the possibility of TOI-733 b being a highly irradiated ocean world, adding a watery twist to its mystique.
Comparing Cosmic Cousins
TOI-733 b shares intriguing similarities with another cosmic counterpart, π Men c. Both planets receive a comparable amount of stellar irradiation and orbit stars of similar type and age. Models suggest that water (H2O) plays a significant role in their composition. Recent observations hint at this being a common trait among such planets, adding to the intrigue.
Unanswered Questions
The enigma of TOI 733b doesn't stop at its composition. A burning question in the realm of exoplanet science is whether it possesses a secondary atmosphere or is indeed an ocean planet from its inception. Solving this puzzle could reshape our understanding of exoplanets and their evolution.
Unlocking the Cosmic Mysteries
