Just how "locked" are resonant-chains of exoplanets thought to be? (e.g. K2-138 and TOI-178)

Short Answer: MMR (Mean Motion Resonance) chains seem to be mostly unstable over the lifetime of a planetary system, since we suspect most planetary systems begin in some resonance lock, but we ...

Deep-CEE I data

The authors used the SDSS (Sloan Digital Sky Survey) III dataset (data release 9): We use a state-of-the-art probabilistic algorithm, adapted to localise and classify galaxy clusters from other ...

Photometric redshift

The process of determining photometric redshift includes, e.g.,: 1. objects of interest 2. types of data (e.g., one epoch multiple filters, one filter multiple epochs) 3. method of analysis (including ...

Just how "locked" are resonant-chains of exoplanets thought to be? (e.g. K2-138 and TOI-178)

Is it known yet how long-lived (time domain) or narrow (frequency) domain these resonances are, or are likely to be? In other words, are they thought to be really "locked" into these fixed ...

Do researchers create their own convolutional neural network models for their work or do they use existing ones (e.g. YOLO, detectron2, etc)

It depends, if astronomers are just identifying which star, which arm, using preexisting datasets like GalaxyZoo, they use preexisting neural networks. But for more complex tasks such as find the ...
