On the orbital decay of the PSR J0045-7319 Binary
Pawan Kumar, Eliot J. Quataert
Recent observations of PSR J0045-7319, a radio pulsar in a close eccentric orbit with a massive main sequence B-star companion, indicate that the system's orbital period is decreas…
Excitation of Solar Acoustic Oscillations
Pawan Kumar
The stochastic excitation of solar oscillations due to turbulent convection is reviewed. A number of different observational results that provide test for solar p-mode excitation t…
HI Observations of two Molecular Clouds with Extremely Large Velocity Dispersions
Harald Riffert, Pawan Kumar, W. K. Huchtmeier
We have mapped two molecular clouds at (l, b) = (3.2 degrees, + 0.3 degrees) and (l, b) = (5.4 degrees, -0.5 degrees) in 21-cm line and continuum emission. These clouds show unusua…
Angular momentum transport by gravity waves and its effect on the rotation of the solar interior
Pawan Kumar, Eliot J. Quataert
We calculate the excitation of low frequency gravity waves by turbulent convection in the sun and the effect of the angular momentum carried by these waves on the rotation profile…
Differential rotation enhanced dissipation of tides in the PSR J0045-7319 Binary
Pawan Kumar, Eliot J. Quataert
Recent observations of PSR J0045-7319, a radio pulsar in a close eccentric orbit with a massive B-star companion, indicate that the system's orbital period is decreasing on a times…
Asymmetries of Solar p-mode Line Profiles
Pawan Kumar, Douglas Abrams
Recent observations indicate that solar p-mode line profiles are not exactly Lorentzian, but rather exhibit varying amounts of asymmetry about their respective peaks. We analyze p-…
