A transiting exocomet detected in broadband light by TESS in the β Pictoris system
This repository containts various files, which were used for the paper Zieba et al. (2019).
This repository containts the following folders:
Contains the Jupyter Notebook with was used for the MCMC routine.
Contains the light curve and target pixel files of beta Pictoris for Sector 4 through 7 downloaded from the MAST archive.
Contains three plots which also can be found in the publication and two Jupyter Notebooks:
betaPic_lightkurve.ipynb analyses beta Pictoris using the
construction_of_the_lightcurve.ipynb uses the files in mast_files. We also take a look at the closest stars using the
Contains four short (each ~1min and ~10MB) movies of beta Pictoris created by cutting out a 60x60 pixel area around the star using a jupyter notebook (which also can be found there). The mid-exposure time is marked just above the animation in BTJD (BJD - 2457000). Every movie shows the observations of beta Pic for a specific sector. No background objects (asteroids, ...) are visible before, during or after the dimming events. The flash-like events every approx. 3 days are caused by the momentum dumps.
