All things – from planets to needle-shaped rocks – in motion around their star (or other stars!) are narrating an interesting story about their history. Are we listening? Come attend Dr. Greg Laughlin’s plenary lecture at #AAS233 to know more!
On the third day of Christmas the ALMA gave to me, 20 highly resolved protoplanetary disks!
What do the atmospheres of ultra-hot Jupiters and 70s music have in common? A good deal of metal.
Mapping the atmospheres and surfaces of exoplanets is ailed by degeneracies due to the choice of map structure and orbital parameter uncertainties. Today’s paper attempts to solve this by using a principal component analysis approach.
Scrutinizing a popular method of characterizing exoplanet atmospheres reveals an inherent degeneracy that may only be overcome in special cases.
