ABSTRACT We statistically validated a sample of hot Neptune candidates applying a two-step vetting technique using dave and triceratops. We performed a systematic validation of 250 transit-like events in the Transiting Exoplanet Survey Satellite archive in the parameter region defined by $P\le 4\, \text{d}$ and $3\, {\rm R}_{⊕ }\le R \le 5\, {\rm R}_{⊕ }$. Through our analysis, we identified 18 hot Neptune-sized candidates, with a false positive probability ${\lt}50{{\ \rm per\ cent}}$. Nine of these planet candidates still need to be confirmed. For each of the nine targets, we retrieved the stellar parameters using ARIADNE and derived constraints on the planetary parameters by fitting the light curves with the juliet package. Within this sample of nine candidates, we statistically validated (i.e. with false positive probability ${\lt}0.3{{\ \rm per\ cent}}$) two systems (TOI-277 b and TOI-1288 b) by re-processing the candidates with triceratops along with follow-up observations. These new validated exoplanets expand the known hot Neptunes population and are high-priority targets for future radial velocities follow-up.
