Topic-Contributed Paper Session

Music City Center

I will discuss the problem of detecting and characterizing solar and stellar flares in time series data from multiple observatories. The flares occur stochastically, but are sometimes clustered, and always occur over an existing emission process which makes it difficult to disentangle them from baseline emission. I will discuss flares seen in high-energy X-ray data from the Chandra X-ray Observatory as well as optical light curves from TESS.
