A Moist Exoplanet in the Neptune Desert

A Moist Exoplanet in the Neptune Desert

Water vapor detection of exoplanet atmospheres has been a hot topic. This scientific question is included in the first set of results published by JWST. But it’s even more difficult to detect the presence of water vapor on exoplanets in the Neptune desert. This year, researchers detected water vapor on TOI-674 b for the first time by analyzing atmospheric transmission spectrum. It’s very exciting. This discovery provides an important target for subsequent detection with higher precision by JWST.

UR: The Atomic Dark Matter Model: A Possible Solution to the Shortcomings of CDM

Could dark matter behave similarly to regular matter? If so, could dark matter halos collapse and form structures, like a black hole? In this work we explore the Atomic Dark Matter Model and predicting structure formation in it using simple algebra. We build on the current literature by showing that for certain values of the variables that govern dark matter interactions, we won’t be able to determine if the halo will be able to collapse using methods to track the dark matter number densities and how efficiently the halo can dispose of its initial energy.
