Magnetospheric eclipses in the double pulsar system J0737-3039
Roman R. Rafikov, Peter Goldreich
We argue that eclipses of radio emission from the millisecond pulsar A in the double pulsar system J0737-3039 are due to synchrotron absorption by plasma in the closed field line r…
Effects of Gravitational Lensing in the Double Pulsar System J0737-3039
Dong Lai, Roman R. Rafikov
We investigate the effects of gravitational lensing in the binary pulsar system J0737-3039. Current measurement of the orbital inclination allows the millisecond pulsar (A) to pass…
Can giant planets form by direct gravitational instability?
Roman Rafikov
Gravitational instability has been invoked as a possible mechanism of giant planet formation in protoplanetary disks. Here we critically revise its viability by noting that for the…
Atmospheres of protoplanetary cores: critical mass for nucleated instability
Roman Rafikov
We study quasi-static atmospheres of accreting protoplanetary cores for different opacity behaviors and realistic planetesimal accretion rates in various parts of protoplanetary ne…
