[Seeking Endorsement] I have characterized a rocky Earth analog in the habitable zone of a solar-type star, but I need help uploading the preprint to arXiv.
Hello r/exoplanets,
I have been working on the physical characterization of a Kepler Object of Interest (KOI) candidate identified using a LightGBM binary classifier applied to the NASA Exoplanet Archive. After running a 100,000-sample Monte Carlo simulation combining Kepler photometry and Gaia DR3 astrometry, the results suggest it is a high-priority target.
I don't want to reveal the exact identifier just yet, but here are the physical characteristics I have been able to constrain:
- Host Star: The candidate orbits a G-type yellow dwarf, very similar to our own Sun.
- Orbital Period: Its "year" lasts 432.43 ± 0.04 days.
- Radius and Mass: It has a measured radius of $1.14 \pm 0.37~R_{\oplus}$. My probabilistic model yields a median mass of 1.36 $M_{\oplus}$.
- Composition: This gives a bulk density of 5.25 g/cm³. In other words, it is fully consistent with a terrestrial composition.
- Insolation and Habitability: The planet receives 1.07 $S_{\odot}$ of stellar radiation. This places it directly within the optimistic habitable zone.
- Potential Climate: Assuming Earth-like greenhouse forcing, the projected median surface temperature is 292 K. In 58.3% of the simulated scenarios, conditions permit liquid water.
- Benign Environment: Unlike habitable-zone candidates around red dwarfs, this system does not face tidal locking issues due to its wide orbit. Furthermore, the expected X-ray and EUV flux environment is remarkably benign, avoiding extreme atmospheric stripping.
In short, it boasts a deterministic Earth Similarity Index ($ESI = 0.90$) that positions it among the most promising candidates orbiting G-type stars.
My current problem: I have the paper with the detailed physical characterization ready to publish. However, as an independent researcher, the arXiv system requires an endorsement code from an established author to publish in the astro-ph.EP (Earth and Planetary Astrophysics) category.
Does anyone in the community have the privileges to endorse in this category, or could you guide me on the best way to get one? I am more than willing to send the draft document via private message so you can evaluate the quality of the methodology before committing to anything.
Any help or suggestions are welcome!
