Can super-rotating oceans cool off extreme exoplanets?

The article concludes "But still, super-rotation of ocean currents on tidally locked exoplanets is certainly possible, which is a relief for any hopes and dreams of alien life on those exoplanets. The more their atmospheres and oceans can transport heat around those worlds, the better chance life has for thriving."

Perhaps someday an exoplanet like this with super-rotation of ocean currents will be confirmed. Presently, various exoplanets found orbiting red dwarf stars pose serious challenges to abiogenesis taking place on them (the assumption to explain the origin of life) and life continuing to evolve on the exoplanet. Here is an example. This exoplanet seems to have no atmosphere, dayside temps near 1040 K, night side temps near 0 K, LHS 3844 b.

Volcanoes might light up the night sky of this exoplanet, https://phys.org/news/2021-03-volcanoes-night-sky-exoplanet.html and http://exoplanet.eu/catalog/lhs_3844_b/ provides a view of exoplanet and host star metrics. The host star is 0.154 solar masses. Orbital period of LHS 38444 b is ~ 0.46 days, a = 0.00623 au. The NASA ADS Abstract indicates little or no atmosphere on this exoplanet, https://ui.adsabs.harvard.edu/abs/2021arXiv210302374M/abstract, March 2021, arXiv paper attached.

From the arXiv paper Introduction “Since the first thermal map of a super-Earth was constructed for super-Earth 55 Cnc e (Demory et al. 2012, 2016), other super-Earths have been targeted with observations to constrain their thermal emission and thus constrain their day- and nightside temperatures. Recent efforts focused on LHS 3844b have found coincidence between the substellar point and the observed hotspot, and inferred a dayside temperature of 1040 +/- 40 K and a nightside temperature around 0 K (Kreidberg et al. 2019). These suggest that heat redistribution is inefficient; therefore the planet has neither substantial melt at its surface nor an active atmosphere."

Looking for super-rotation oceans on exoplanets moving around red dwarfs is challenging. Demonstrating abiogenesis operating on those exoplanets is more challenging and have life on them.

Presently we find exoplanets like LHS 38444 b at red dwarf stars.
