All planets but the innermost one form a 2:4:6:9:12 chain of Laplace resonances, and the planetary densities show important variations from planet to planet, jumping from 1. 02(+0. 28/-0. 23) to 0. 177(+0. 055/-0. 061) times the Earth's density between planets c and d. Using Bayesian interior structure retrieval models, we show that the amount of gas in the planets does not vary in a monotonous way, contrary to what one would expect from simple formation and evolution models and unlike other known systems in a chain of Laplace resonances.

FORS-Up: Making the most versatile instrument in Paranal ready for 15 more years of operations

no code implementations16 Dec 2020 H. M. J. Boffin, F. Derie, A. Manescau, R. Siebenmorgen, V. Baldini, G. Calderone, R. Cirami, I. Coretti, P. Di Marcantonio, J. Kolsmanski, P. Lilley, S. Moehler, M. Nonino, G. Rupprecht, A. Silber

The project - carried out as a collaboration between ESO and INAF-Astronomical Observatory of Trieste - aims at bringing to the telescope in 2023/2024 a refurbished instrument with a new scientific detector, an upgrade of the instrument control software and electronics, a new calibration unit, as well as additional filters and grisms.
