PLANETARY SYSTEMS OF THE GALAXY
Odessa Astronomical Publications, 2017 Definition of planets, relative contents of planetary systems in Galaxy, and main results of searching for them are adduced. It is supposed to distinguish four types of planets accordingly their inner substance composition: hydrogenous-helium (H2 , He ...

A magnetic thrust action on small bodies orbiting a pulsar [PDF]
, 2011 We investigate the electromagnetic interaction of a relativistic stellar wind with small bodies in orbit around the star. Based on our work on the theory of Alfv\'en wings to relativistic winds presented in a companion paper, we estimate the force ...

Neutron Star Planets: Atmospheric processes and habitability [PDF]
, 2017 Of the roughly 3000 neutron stars known, only a handful have sub-stellar companions. The most famous of these are the low-mass planets around the millisecond pulsar B1257+12.

Taxonomy of the extrasolar planet
, 2012 When a star is described as a spectral class G2V, we know that the star is similar to our Sun. We know its approximate mass, temperature, age, and size.

Towards a theory of extremely intermittent pulsars II: Asteroids at a close distance [PDF]
, 2013 We investigate whether there may be one or many companions orbiting at close distance to the light cylinder around the extremely intermittent pulsars PSR B1931+24 and PSR J1841-0500.

Is There a Planet in the PSR 1620-26 Triple System?
, 1994 The unusually large eccentricity ($e_1=0.025$) of the low-mass binary millisecond pulsar PSR B1620-26 can be explained naturally as arising from the secular perturbation of a second, more distant companion.

Similarities Between the Inner Solar System and the Planetary System of PSR B1257+12 [PDF]
, 1994 We call attention to the surprising similarity between the newly discovered planetary system around PSR B1257+12 and the inner solar system. The similarity is in the ratios of the orbital radii and the masses of the three planets.Comment: 4 pages ...

A Search for Cold Dust around Neutron Stars
, 2004 We present observations of nine radio pulsars using the Heinrich-Hertz-Telescope at \lambda 0.87mm and the IRAM 30-m telescope at \lambda 1.2mm in search for a cold dust around these sources.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range
Wildlife Society Bulletin, EarlyView.We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

The Evolution of Protoplanetary Disks Around Millisecond Pulsars: The PSR 1257 +12 System
, 2007 We model the evolution of protoplanetary disks surrounding millisecond pulsars, using PSR 1257+12 as a test case. Initial conditions were chosen to correspond to initial angular momenta expected for supernova-fallback disks and disks formed from the ...
