We present measurements of the true masses and orbital inclinations of the two Earth-mass planets in the PSR B1257+12 system, based on the analysis of their mutual gravitational perturbations detectable as microsecond variations of the arrival times of radio pulses from the pulsar. The 6.2 ms pulsar, PSR B1257+12, has been regularly timed with the Arecibo telescope since late 1990. Assuming the standard pulsar mass of 1.4 M☉, the derived masses of planets B and C are 4.3 ± 0.2 and 3.9 ± 0.2 M… 

Phenomenological constraints on accretion of non-annihilating dark matter on the PSR B1257+12 pulsar from orbital dynamics of its planets

We analytically compute the effects that a pulsar's mass variation, whatever its physical origin may be, has on the standard Keplerian changes ΔτKep in the times of arrival of its pulses due to

Constraining the relative inclinations of the planets B and C of the millisecond pulsar PSR B1257+12

We investigate on the relative inclination of the planets B and C orbiting the pulsar PSR B1257+12. First, we show that the third Kepler’s law does represent an adequate model for the orbital periods

Fifteen years of the neutron star planet research

Developments in the investigations of the known planets around two millisecond radio pulsars, PSR B1257+12 and PSR B1620−26, and in the searches for dusty disks around pulsars are discussed and

Long-Term Stability and Dynamical Environment of the PSR 1257+12 Planetary System

We study the long-term dynamics of the PSR 1257+12 planetary system. Using the recently determined accurate initial condition by Konacki & Wolszczan, who derived the orbital inclinations and the

Planets Around Neutron Stars

The objective of this proposal was to continue investigations of neutron star planetary systems in an effort to describe and understand their origin, orbital dynamics, basic physical properties and

PSR J2322−2650 – a low-luminosity millisecond pulsar with a planetary-mass companion

We present the discovery of a binary millisecond pulsar (MSP), PSR J2322−2650, found in the southern section of the High Time Resolution Universe survey. This system contains a 3.5-ms pulsar with a

Eclipse, transit and occultation geometry of planetary systems at exo-syzygy

Although conjunctions and oppositions frequently occur in planetary systems, eclipserelated phenomena are usually described from an Earth-centric perspective. Space missions to different parts of the

Merger of a White Dwarf-Neutron Star Binary to $10^{29}$ Carat Diamonds: Origin of the Pulsar Planets

We show that the merger and tidal disruption of a C/O white dwarf (WD) by a neutron star (NS) binary companion provides a natural formation scenario for the PSR B1257+12 planetary system. Starting

Very long baseline interferometry astrometry of PSR B1257+12, a pulsar with a planetary system

An astrometry project on PSR B1257+12, a millisecond pulsar with a planetary system, has been carried out with the Very Long Baseline Array and the European Very Long Baseline Interferometry (VLBI)

Constructing a Pulsar Timing Array

Arrival time data from a spatial array of millisecond pulsars can be used (1) to provide a time standard for long time scales, (2) to detect perturbations of the earth's orbit, and (3) to search for

Confirmation of Earth-Mass Planets Orbiting the Millisecond Pulsar PSR B1257 + 12

The unambiguous detection of this effect, after 3 years of systematic timing observations of PSR B1257+12 with the 305-meter Arecibo radiotelescope, constitutes irrefutable evidence that the first planetary system around a star other than the sun has been identified.

Searches for Planets Around Neutron Stars

We review the methodology of searches for planet-mass bodies around neutron stars observable as radio pulsars and discuss the current status of these searches. PSR B1257 + 12, a 6.2-millisecond

Timing Observations of Four Millisecond Pulsars with the Arecibo and Effelsberg Radio Telescopes

We present long-term timing observations of four millisecond radio pulsars with the 305 m Arecibo and the 100 m Effelsberg radiotelescopes. Our analysis of the combined pulse time-of-arrival data

Planets around massive white dwarfs

One of the models for the formation of planets around pulsars suggests that the pulsar formed from the merger of two white dwarfs and the planets from the resulting debris. It is pointed out here

Discovery of Four Isolated Millisecond Pulsars

We report the discovery of four isolated millisecond pulsars found as part of the Parkes 436 MHz survey of the southern sky. Three of the pulsars, PSRs J1024-0719, J1744-1134, and J2124-3358, are

Three-body effects in the PSR 1257+12 planetary system

A detailed theoretical analysis of the three-body effects in the putative planetary system of PSR 1257+12 is presented. Ways in which these effects are manifested in the pattern of pulse arrival

On the verification of the planetary system around PSR 1257 + 12

The magnitude and nature of residuals expected in the times of pulsar arrival (TOA) of the millisecond pulsar PSR 1257 + 12 as a function of the observational time span is estimated so that an

Neutron stars and planet-mass companions

A formation mechanism is proposed for the recently discovered planet-mass companions to neutron stars, namely that the stellar companion of a millisecond pulsar is disrupted by rapid mass loss via an
