On the Determination of Planetary Masses [PDF]
A common method of determining the mass of a planet is to solve for the orbit of some other object several times with different trial values for the mass in question. It is pointed out that a parabola fitted to the values of the sums of the squares of the residuals may be used to obtain, not only the planetary mass, but also its probable error. Marsden'

Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70 [PDF]
Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chemical conditions under which planet formation takes place.

ALMA Observations of the Young Substellar Binary System 2M1207 [PDF]
We present ALMA observations of the 2M1207 system, a young binary made of a brown dwarf with a planetary-mass companion at a projected separation of about 40 au.

Bayesian test of the mass of the graviton with planetary ephemerides
In this work, we investigated Bayesian methodologies for constraining in the Solar System a Yukawa suppression of the Newtonian potential -- which we interpret as the effect of a non-null graviton mass -- by considering its impact on planetary orbits.

The magnetic activity of a star—which modulates the stellar wind outflow—shapes the immediate environments of orbiting (exo)planets and induces atmospheric loss, thereby impacting their habitability.

Properties of the Planetary Caustic Perturbation [PDF]
Just two of 10 extrasolar planets found by microlensing have been detected by the planetary caustic despite the higher probability of planet detection relative to the central caustic which has been responsible for four extrasolar planet detections.

We present the analysis of seven microlensing planetary events with planet/host mass ratios q < 10 ^−4 : KMT-2017-BLG-1194, KMT-2017-BLG-0428, KMT-2019-BLG-1806, KMT-2017-BLG-1003, KMT-2019-BLG-1367, OGLE-2017-BLG-1806, and KMT-2016-BLG-1105.

Constraining the Mass of the Graviton with the Planetary Ephemeris INPOP [PDF]
We use the planetary ephemeris INPOP17b to constrain the mass of the graviton in the Newtonian limit. We also give an interpretation of this result for a specific case of fifth force framework. We find that the residuals for the Cassini spacecraft significantly (90\% C.L.) degrade for Compton wavelengths of the graviton smaller than $1.83\times 10^{13}$
