Center for Astrophysics Research and Technologies Seminar Series
Orbital Evolution Studies and Radio Searches of Extra-Solar Moons
Presented by Marialis Rosario-Franco (UTA/NRAO)
Understanding the constraints under which extra-solar moons form around exoplanets can provide insight into the overall formation of the system, the host planet's habitability, and could even aid the process of drawing out the best observational candidates for exomoon searches. Motivated by this, we study post-massive impact scenarios of moons in stellar systems to evaluate their orbital evolution. We aim to understand the conditions under which exomoons and submoons could be stable in order to draw candidates for radio-observations. We extend our numerical approach to observational by applying a novel radio-detection method, proposed by Noyola et al. (2014). This method is based on a planet-moon interaction observed between the Jupiter-Io system, where Io-controlled decametric emissions are used to determine how the presence of exomoons might be revealed by the same modulation mechanism. Observations of 3 nearby (~4.6 pc) planetary systems, performed through the Giant Metrewave Radio Telescope (GMRT) at 325 MHz, are analyzed and presented. Follow up observations at low frequencies, performed with the Long Wavelength Array (LWA) are discussed along with preliminary results of our numerical studies.
