Scorching Neptune-size world is way too massive for astronomers to explain

"The newfound planet's diameter is about 3.46 times larger than Earth's, making it a bit smaller than Neptune, which is about 3.8 times wider than Earth. However, upon using Italy's Galileo National Telescope on the island of La Palma to measure the strength of TOI-1853 b's gravitational tug on its star, the scientists estimated this exoplanet's mass is about 73 times greater than Earth's. This means its mass is nearly equal to the mass of Saturn, which is about 95 times more massive than Earth. All in all, TOI-1853 b is about six times denser than Neptune and nearly twice as dense as Earth. This makes it the densest Neptune-size planet known to date."

My note, properties for TOI-1853 b are listed at this site,

However, the mass is 0.040571 Mjup or about 12.89 earth masses. I do not see this listed at
Using radial velocity methods for determining exoplanet masses is important and requires very good properties for the host star too, otherwise various exoplanets masses could be calculated with errors.

Refining the Stellar Parameters of τ Ceti: a Pole-on Solar Analog,

"To accurately characterize the planets a star may be hosting, stellar parameters must first be well-determined. τ Ceti is a nearby solar analog and often a target for exoplanet searches. Uncertainties in the observed rotational velocities have made constraining τ Ceti's inclination difficult. For planet candidates from radial velocity (RV) observations, this leads to substantial uncertainties in the planetary masses, as only the minimum mass (msini) can be constrained with RV..."
