“…Any direction in the tangent plane is specified by the position angle reckoned from north to east, i.e., counterclockwise fromq top. The general consideration of the Keplerian orbits can be found in many books (e.g., Heintz, 1978;Kopeikin et al, 2011;Perryman, 2011). Orbits are conventionally parameterized by means of the six Keplerian elements.…”

High-precision observations require accurate modeling of secular changes in the orbital elements in order to extrapolate measurements over long time intervals, and to detect deviation from pure Keplerian motion caused, for example, by other bodies or relativistic effects. We consider the evolution of the Keplerian elements resulting from the gradual change of the apparent orbit orientation due to proper motion. We present rigorous formulae for the transformation of the orbit inclination, longitude of the ascending node and argument of the pericenter from one epoch to another, assuming uniform stellar motion and taking radial velocity into account. An approximate treatment, accurate to the second-order terms in time, is also given. The proper motion effects may be significant for long-period transiting planets. These theoretical results are applicable to the modeling of planetary transits and precise Doppler measurements as well as analysis of pulsar and eclipsing binary timing observations.

“…A second reason is that the astrophysical information to be detected or estimated is often not directly related to the data. For instance, information like the mass of an extrasolar planet, the distance to its host star, or even simply its very existence can sometimes be revealed only by means of sophisticated detection and estimation algorithms in time series [Perryman, 2011] or images [Starck et al, 2015]. Information like the internal structure of pulsating stars, their age, radius and effective temperature can be evaluated by 1 comparing the detected oscillation modes with numerical models [ChristensenDalsgaard, 2003[ChristensenDalsgaard, , 2008.…”

“…Over the last two decades, about 4000 exoplanets have been discovered around lowmass stars (Perryman 2018). In close-in star-planet systems, tidal dissipation in the host star is known to affect the semi-major axis (and thus the orbital period) of the companion as well as the spin of the star over secular timescales (see e.g.…”

The impact of magnetism on tidal dynamics in the convective envelope of low-mass stars

et al. 2019

For the shortest period exoplanets, star-planet tidal interactions are likely to have played a major role in the ultimate orbital evolution of the planets and on the spin evolution of the host stars. Although low-mass stars are magnetically active objects, the question of how the star’s magnetic field impacts the excitation, propagation and dissipation of tidal waves remains open. We have derived the magnetic contribution to the tidal interaction and estimated its amplitude throughout the structural and rotational evolution of low-mass stars (from K to F-type). We find that the star’s magnetic field has little influence on the excitation of tidal waves in nearly circular and coplanar Hot-Jupiter systems, but that it has a major impact on the way waves are dissipated.
