Hourly radio variability of PDS70c from time-differential photometry
Simon Casassus, Miguel Carcamo, Oriana Dominguez-Jamett +5
The radio emission mechanisms from accreting protoplanets, and their variability, link observations and physical properties. We revisit the variability of the ~343GHz (ALMA Band7)…
A revision of the lifetime of submoons: tidal dynamics with the Euler-Lagrange equation
Iason Saganas, Grant Mayberry, Barbara Ercolano
Submoons, moons orbiting other moons, may be exotic environments capable of hosting extraterrestrial life. We extend previous studies to revise the maximum lifetime of these object…
Multi-frequency observations of PDS 70c: Radio emission mechanisms in the circum-planetary environment
Oriana DomÃnguez-Jamett, Simon Casassus, Hauyu Baobab Liu +7
PDS 70c is a source of Ha emission and variable sub-mm signal. Understanding its emission mechanisms may enable observations of accretion rates and physical conditions in the circu…
Probing accretion and stellar properties in the Orion Nebula with VLT/X-Shooter
L. Piscarreta, G. Beccari, R. A. B. Claes +6
Multiple photometric studies have reported the presence of seemingly older accreting pre-main sequence stars (PMS) in optical colour-magnitude diagrams (CMDs). We investigate this…
