We analytically work out the long-term variations caused on the motion of a planet orbiting a star by a very distant, pointlike massive object X. Apart from the semi-major axis a, all the other Keplerian osculating orbital elements experience long-term variations which are complicated functions of the orbital configurations of both the planet itself and of X. We infer constraints on the minimum distance dX at which X may exist by comparing our prediction of the long-term variation of the… 

Constraining the Angular Momentum of the Sun with Planetary Orbital Motions and General Relativity

The angular momentum of a star is an important astrophysical quantity related to its internal structure, formation, and evolution. Helioseismology yields $S_{\odot}= 1.92\times10^{41}\ \mathrm{kg\

EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM

Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion. While several

Constraints on the location of a possible 9th planet derived from the Cassini data

To explain the unusual distribution of Kuiper belt objects, several authors have advocated the existence of a super-Earth planet in the outer solar system. It has recently been proposed that a 10 M⊕

The fates of Solar system analogues with one additional distant planet

The potential existence of a distant planet (“Planet Nine”) in the Solar system has prompted a re-think about the evolution of planetary systems. As the Sun transitions from a main sequence star into

OBSERVATIONAL CONSTRAINTS ON PLANET NINE: ASTROMETRY OF PLUTO AND OTHER TRANS-NEPTUNIAN OBJECTS

We use astrometry of Pluto and other trans-neptunian objects to constrain the sky location, distance, and mass of the possible additional planet (Planet Nine) hypothesized by Batygin & Brown. We find

Constraints on Non-Standard Gravitomagnetism by the Anomalous Perihelion Precession of the Planets

In 2008, a team of astronomers reported an anomalous retrograde precession of the perihelion of Saturn amounting to _ !SATURN = 0:006(2) arcsec per century (arcsec cy 1 ). This unexplained precession

FORMATION OF SUPER-EARTH MASS PLANETS AT 125–250 AU FROM A SOLAR-TYPE STAR

We investigate pathways for the formation of icy super-Earth mass planets orbiting at 125–250 AU around a 1 M ⊙ ?> star. An extensive suite of coagulation calculations demonstrates that swarms of 1

In a geocentric kinematically rotating ecliptical coordinate system in geodesic motion through the deformed spacetime of the Sun, both the longitude of the ascending node and the inclination of an

Perspectives on effectively constraining the location of a massive trans-Plutonian object with the New Horizons spacecraft: a sensitivity analysis

The radio tracking apparatus of the New Horizons spacecraft, currently traveling to the Pluto system where its arrival is scheduled for July 2015, should be able to reach an accuracy of 10 m (range)

The Solar System's Post-Main Sequence Escape Boundary

The Sun will eventually lose about half of its current mass non-linearly over several phases of post-main-sequence evolution. This mass loss will cause any surviving orbiting body to increase its

Constraints on planet X/Nemesis from Solar System's inner dynamics

We use the corrections Δ to the standard Newtonian/Einsteinian perihelion precessions of the inner planets of the Solar system, recently estimated by E.V. Pitjeva by fitting a huge planetary data set

Constraints on the Acceleration of the Solar System from High-Precision Timing

Many astronomers have speculated that the solar system contains undiscovered massive planets or a distant stellar companion. The acceleration of the solar system barycenter can constrain the mass and

The Existence of a Planet beyond 50 AU and the Orbital Distribution of the Classical Edgeworth–Kuiper-Belt Objects

Abstract We study the effects of a Mars-like planetoid with a semimajor axis at about ∼60 AU orbiting embedded in the primordial Edgeworth–Kuiper belt (EKB). The origin of such an object can be

Astrometric Microlensing Constraints on a Massive Body in the Outer Solar System with Gaia

A body in solar orbit beyond the Kuiper Belt exhibits an annual parallax that exceeds its apparent proper motion by up to many orders of magnitude. Apparent motion of this body along the parallactic

Dynamical limits on dark mass in the outer solar system

Simplified model solar systems with known observational errors are considered in conducting a dynamical search for dark mass and its minimum detectable amount, and in determining the significance of

Arguments for the presence of a distant large undiscovered Solar system planet

Aphelion distances of long-period comets show a slight excess around 30 000 to 50 000 au from the Sun. Positions of cometary aphelia within these distance limits are aligned along a great circle

It has been suggested1,2 that the observed periodic extinction of species at intervals of 26 Myr (ref. 3) may be catalysed by a hypothetical stellar companion of the Sun, Nemesis, with an orbital
