Substructures in Planet-Forming Disks with the SKAO
Yinhao Wu, Jessica Speedie, Sebastián Pérez +33
Disks of gas and dust orbiting young stars are the arenas and material reservoirs for planet formation. Over the past decade, multiwavelength observations, from infrared to radio,…
Probing Anomalous Microwave Emission with the Square Kilometre Array
MatÃas Vidal, Simón Casassus, Roke Cepeda-Arroita +15
Anomalous microwave emission (AME) represents an excess of radiation in the 10-60 GHz range, distinct from synchrotron, free-free, or thermal dust emission. Although most commonly…
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)…
The Ophiuchus DIsc Survey Employing ALMA (ODISEA). Substructures as a function of SED Class and disc mass in 100 systems
Trisha Bhowmik, Lucas Cieza, J. M. Miley +17
Current high-resolution studies of protoplanetary discs are biased toward small samples of the brightest (flux > 50 mJy at 225 GHz) and largest systems. We present a complete flux-…
ALMA Band1 observations of the rhoOphW filament I. Enhanced power from excess microwave emission at high spatial frequencies
Simon Casassus, Matias Vidal, Miguel Carcamo +3
The rhoOphW photo-dissociation region (PDR) is an example source of bright excess microwave emission (EME), over synchrotron, free-free, and the Rayleigh-Jeans tail of the sub-mill…
Impact of embedded circumplanetary winds on the circumstellar disk: I. Reshaping the local accretion environment
Danilo Sepúlveda-Rojas, Pablo BenÃtez-Llambay, Simon Casassus
The existence of winds is among the uncertainties related to the growth of giant planets. Such circumplanetary outflows have been proposed to explain kinematic and chemical structu…
