Planetary Mass and Metallicity Derived Directly from Transmission Spectroscopy

, 2020
The mass of an exoplanet is its most fundamental property. Currently, masses are typically determined via the radial velocity (RV) technique (since the transit-timing variation method requires special planetary systems); unfortunately, sufficiently ...

A time-dependent variation–perturbation method for the calculation of transition properties and its relation to the random phase approximation

The Journal of Chemical Physics, 1975
A time−dependent variation−perturbation (VP) formulation is presented for the simultaneous calculation of the ground state correlation function and the excited state wave function of an atomic or molecular system. The wave functions are chosen for the optimal calculation of transition properties with a relatively small number of molecular integrals ...

Solar astrometry with planetary transits

Proceedings of the International Astronomical Union, 2019
Planetary transits are used to measure the solar radius since the beginning of the 18th century and are the most accurate direct method to measure potentially long-term variation in the solar size.

Astronomy. Star-crossing planets literally strut their stuff.

Science, 2014
Exoplanet hunters announced last week that they had found a tribe of "mini-Neptunes" and the lightest planet ever detected outside our solar system. The results show the power of an up-and-coming method of calculating the masses of alien worlds from the ...
