Planets around Pulsars

AIP Conference Proceedings, 2011
In 1992 the first extrasolar planets were discovered. But unlike expected, these planets were not located around normal stars. The central object of the system that is now known to consist of (at least) three planets, is a radio pulsar. This discovery was possible due to the unique precision of pulsar timing which allows us to detect even asteroid ...

Planets Around Pulsars: A Review

Astrophysics and Space Science, 1994
The discovery last year of a planetary system orbiting a millisecond pulsar raises important questions in pulsar evolution, planet formation, and planetary dynamics. We review the literature concerning pulsar-planetary systems, emphasizing particularly the contributions to the meeting Planets around Pulsars held at Caltech in 1992.

Planets around pulsar: Formation and evolution

Il Nuovo Cimento B, 2007
The existence of planetary systems around pulsars, in particular PSR 1257+12 and PSR 1620-26, is not completely comprehensible within the standard picture that considers pulsars as a consequence of supernova explosions. However, it is possible to look for alternative scenarios in which planetary systems around pulsars may form and evolve.

Conditions for Pulsar Planet Formation

2021
This paper outlines the conditions for planet formation around pulsars. A common model proposes the fallback of mass after an initial supernova explosion, which occurs as a reverse shock propagates the inward accretion of a fraction of bound material back onto the surface of the star.

Discovery of pulsar planets

New Astronomy Reviews, 2012
Abstract In this paper I recount the events which have led to the discovery of the first planets beyond the Solar System. The two planets circling an old neutron star, the 6.2 ms pulsar PSR B1257+12, were discovered in 1991 with the 1000 ft Arecibo radio telescope.

The origin of planets orbiting millisecond pulsars

Nature, 1992
A model for the formation of planets around millisecond pulsar which no longer have stellar companions is suggested. Detailed hydrodynamical models are presented which suggest that planet formation can occur either in a low-mass X-ray binary progenitor to a progenitor of a star-vaporizing millisecond pulsar when the neutron star is accreting material ...

Pulsar planet di massa terrestre: esotici e rari

2022
Passando al setaccio i dati di archivio di 800 pulsar osservate dal Jodrell Bank Observatory negli ultimi 50 anni, un team di astronomi della University of Manchester ha scoperto che i pianeti di massa terrestre in orbita attorno alle pulsar sono estremamente rari. Ciò spiegherebbe perché Psr B1257+12, scoperto trent’anni fa, rimanga l’unico sistema di
