According to one theory of planet formation, the secret to forming massive planets is through itsy-bitsy, teeny-weeny pebbles of dust. In today’s astrobite, we explore what sort of planets these little pebbles could form.
We need to know the radii of M-dwarfs to study their exoplanets, and the models aren’t much help.
Is string theory compatible with observational data? Today’s paper looks at how avoiding the swampland of unsuccessful string theories can mean violating reliable constraints on cosmological quantities.
How can Gaia and 2MASS magnitudes help in sorting AGB stars?
Can the properties of a known planet system predict if that system has additional undetected planets?
