Randomized trial measures radio emissions from PDS 70c, indicating variability linked to protoplanetary processes.

This research examines the time-variable radio emissions from the protoplanet PDS 70c.
Utilized time-differential photometry and visibility alignment from ALMA observations.
Analyzed data from both the 2017 and 2023 ALMA datasets.
Conducted statistical tests to assess the significance of variability.
Detected a 228% increase in flux density on December 6, 2017 (3.3σ).
Showed a 170% rise with significant scatter split into 20-min intervals (2.6σ).
Found constant flux densities within a scatter of ∼15% in the 2023 dataset.

Casassus et al. (2026) studied this question.
