Long-period radio transient PSR J0901-4046 is not an Isolated White Dwarf Pulsar
Maxim Lyutikov, Mukremin Kilic, Alexander Wolszczan +1
We report the {\it Chandra} non-detection of PSR J09014046, a seconds long-period radio transient (LPT). For a distance of 467 pc, the upper limit on X-ray luminosity…
Scintillation of the first-known pulsar planetary system
J. M. Yao, L. Zhang, A. Wolszczan +8
We present a scintillation study of the first-known pulsar planetary system, PSR~B1257+12, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). A total of 31 obs…
Exoplanetary radio emission predictions and detectability in the SKA era
Mahdiyar Mousavi-Sadr, Fatemeh S. Tabatabaei, Alexander Wolszczan +1
Radio observations provide a window into a planet's interior and play a crucial role in studying its atmosphere and surface, key factors to find potential habitability. The discove…
Sensitive Constraints on Coherent Radio Emission from Five Isolated White Dwarfs
Lei Zhang, Alexander Wolszczan, Joshua Pritchard +8
Coherent, periodic radio emission from pulsars has been widely interpreted as evidence of neutron stars as strongly magnetized compact objects. In recent years, radio pulses have a…
