Observations and Studies on the Transiting Systems HAT-P-36, XO-2 and WASP-76
We conducted photometric observations for transit events of three exoplanetary systems HAT-P-36, XO-2 and WASP-76 using the 1 m and 2.4 m telescopes at Yunnan Observatories and the 0.85 m telescope at National Astronomical Observatories of China.

The eight-planet Kepler-90 system exhibits the greatest multiplicity of planets found to date. All eight planets are transiting and were discovered in photometry from the NASA Kepler primary mission. The two outermost planets, g ( P _g = 211 days) and h

Detailed Architecture of the L 98-59 System and Confirmation of a Fifth Planet in the Habitable Zone
The L 98-59 system, identified by TESS in 2019, features three transiting exoplanets in compact orbits of 2.253, 3.691, and 7.451 days around an M3V star, with an outer 12.83 day nontransiting planet confirmed in 2021 using ESPRESSO.

APPLICATION OF TRANSIT TIMING VARIATION METHOD (TTV) TO EXOPLANET SYSTEM TrES-3
On the basis of the original photometricdata, the light curves of several transits in the exoplanet system TrES-3 were simulated by Monte Carlo method.Using these curves, the estimates of precise values of mid-transit time were calculated to assess the possibility offinding new planets by timing method in already known exoplanet systems using ground ...

We report the discovery and characterization of a small planet, TOI-1408 c, on a 2.2 day orbit located interior to a previously known hot Jupiter, TOI-1408 b ( P = 4.42 days, M = 1.86 ± 0.02 M _Jup , R = 2.4 ± 0.5 R _Jup ) that exhibits grazing transits.

Kepler-1624b Has No Significant Transit Timing Variations
It is relatively rare for gas giant planets to have resonant or near-resonant companions, but these systems are particularly useful for constraining planet formation and migration models. In this study, we examine Kepler-1624b, a sub-Saturn orbiting an M

Modeling the Solar System. I. Characterization Limits from Analytic Timing Variations
Planetary systems with multiple transiting planets are beneficial for understanding planet occurrence rates and system architectures. Although we have yet to find a solar system (SS) analog, future surveys may detect multiple terrestrial planets ...

TOI-2015 b: A Warm Neptune with Transit Timing Variations Orbiting an Active Mid-type M Dwarf
We report the discovery of a close-in ( P _orb = 3.349 days) warm Neptune with clear transit timing variations (TTVs) orbiting the nearby ( d = 47.3 pc) active M4 star, TOI-2015.
