Volcanic Satellites and Ion Escape in the Magnetospheres of Ultra-Cool and Brown Dwarf Stars
A. F. Lanza, A. V. Oza
Radio emissions at gigahertz frequencies of ultra-cool dwarf and brown dwarf stars suggest the presence of radiation belts not unlike Jupiter's. We investigate the possibility that…
Investigating the visible phase-curve variability of 55 Cnc e
E. A. Meier Valdés, B. M. Morris, B. -O. Demory +87
55 Cnc e is an ultra-short period super-Earth transiting a Sun-like star. Previous observations in the optical range detected a time-variable flux modulation that is phased with th…
Planetary evolution with atmospheric photoevaporation II: Fitting the slope of the radius valley by combining boil-off and XUV-driven escape
Lukas Affolter, Christoph Mordasini, Apurva V. Oza +2
The Kepler satellite has revealed a gap between sub-Neptunes and super-Earths that atmospheric escape models had predicted as an evaporation valley. We seek to contrast results fro…
uGMRT observations of the hot-Saturn WASP 69b: Radio-Loud Exoplanet-Exomoon Survey II (RLEES II)
Mayank Narang, Apurva V. Oza, Kaustubh Hakim +7
Exomoons have so far eluded ongoing searches. Several studies have exploited transit and transit timing variations and high-resolution spectroscopy to identify potential exomoon ca…
Callisto's atmosphere: First evidence for H2 and constraints on H2O
Shane R. Carberry Mogan, Orenthal J. Tucker, Robert E. Johnson +8
We explore the parameter space for the contribution to Callisto's H corona observed by the Hubble Space Telescope (Roth et al. 2017a) from sublimated H2O and radiolytically produce…
Radio-Loud Exoplanet-Exomoon Survey (RLEES): GMRT Search for Electron Cyclotron Maser Emission
Mayank Narang, Apurva V. Oza, Kaustubh Hakim +3
We conducted the first dedicated search for signatures of exoplanet-exomoon interactions using the Giant Metrewave Radio Telescope (GMRT) as part of the radio-loud exoplanet-exomoo…
