Abstract We present the discovery of a low-density planet orbiting high-metallicity early M-dwarf TOI-5688 A b. This was characterized as part search for transiting giant planets ( R ≳ 8 ⊕ ) through Searching Giant Exoplanets around Stars (GEMS) survey. The discovered with Transiting Exoplanet Survey Satellite, and ground-based transits from Red Buttes Observatory, Table Mountain Observatory Pomona College, radial velocity (RV) measurements Habitable-Zone Planet Finder on 10 m Hobby Eberly...
Love numbers measure the reaction of a celestial body to perturbing forces, such as centrifugal force caused by rotation, or tidal forces resulting from interaction with companion body. These parameters are related interior density profile. The non-point mass nature host star and planet orbiting around each other contributes periastron precession. rate this precession is characterized mainly second-order number, which offers an opportunity determine its value. We collected all available...
Abstract Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, all-sky coverage of TESS has enabled detection an increasingly large number them enable statistical surveys like Searching for GEMS survey. As part this endeavor, we describe observations six transiting planets, which include precise mass measurements two (K2-419Ab, TOI-6034b) and validation four systems, includes upper limits three (TOI-5218b, TOI-5616b, TOI-5634Ab), while...
Context. Recent developments in exoplanetary research highlight the importance of Love numbers understanding their internal dynamics, formation, migration history and potential habitability. represent crucial parameters that gauge how exoplanets respond to external forces such as tidal interactions rotational effects. By measuring these responses, we can gain insights into structure, composition, density distribution exoplanets. The rate apsidal precession a planetary orbit is directly...

Abstract Observational data on the dust content of circumstellar disks show that median in around pre-main-sequence stars nearby star-forming regions seems to increase from ∼1 ∼2 Myr and then decline with time. This behavior challenges models where small grains steadily by accumulating into larger bodies drifting inwards a short timescale (≤1 Myr).

We present the discovery of a low-density planet transiting TOI-5688 A b, high-metallicity M2V star. This was discovered as part search for giant planets ($R \gtrsim8$ M$_\oplus$) through Searching GEMS (Giant Exoplanets around M-dwarf Stars) survey. The b with Transiting Exoplanet Survey Satellite (TESS), and characterized ground-based transits from Red Buttes Observatory (RBO), Table Mountain Pomona College, radial velocity (RV) measurements Habitable-Zone Planet Finder (HPF) on 10 m Hobby...

Context . Giant planets are known to dominate the long-term stability of planetary systems due their prevailing gravitational interactions, but they also thought play an important role in planet formation. Observational constraints improve our understanding formation processes such as delivery volatile-rich planetesimals from beyond ice line into inner system. Additional may come studies atmosphere, almost all atmosphere investigate detection certain species, and abundances not routinely...
