TOI-2076 - System
Simulates TOI-2076, an orange K-type dwarf of 0.85 solar masses, and TOI-2076 e, a 4.7-Earth-mass planet, with an orbital period of 3.0 days, at 0.039 AU from its star, and an equilibrium temperature near 1,110 K.
Exoplanets
Four-planet systems that test packing and stability: tightly spaced Kepler chains, hierarchical layouts with a distant giant, and mixed-mass architectures drawn from the archive.

Simulates TOI-2076, an orange K-type dwarf of 0.85 solar masses, and TOI-2076 e, a 4.7-Earth-mass planet, with an orbital period of 3.0 days, at 0.039 AU from its star, and an equilibrium temperature near 1,110 K.

Simulates TOI-4010, an orange K-type dwarf of 0.88 solar masses, and TOI-4010 b, a 11.0-Earth-mass planet, with an orbital period of 1.3 days, at 0.023 AU from its star, and an equilibrium temperature near 1,441 K.

Simulates TOI-561, an ancient thick-disk star about 10 billion years old. Its ultra-short-period rocky planet formed when the Milky Way was young. The inner planet's year lasts only about 10.5 hours.

Simulates TOI-5789, an orange K-type dwarf of 0.82 solar masses, and TOI-5789 b, a 2.1-Earth-mass planet, with an orbital period of 2.8 days, at 0.036 AU from its star, and an equilibrium temperature near 1,201 K.

Simulates TOI-700, TESS's first Earth-sized habitable-zone planet. TOI-700 d orbits a quiet nearby red dwarf together with three inner worlds. TOI-700 e is a second world in the habitable zone.

Simulates V1298 Tau, a 20-million-year-old star with four transiting planets. They are still contracting and look far puffier than mature planets. The star is a young K dwarf in Taurus.
