[ascl:2502.006] Giants: Pipeline to search for exoplanets around evolved stars
Saunders, Nicholas; Grunblatt, Samuel K.; Huber, Daniel; Collins, Karen A.; Jensen, Eric L. N.; Vanderburg, Andrew; Brahm, Rafael; Jordán, Andrés; Espinoza, Néstor; Henning, Thomas; Hobson, Melissa J.; Quinn, Samuel N.; Zhou, George; Butler, R. Paul; Crause, Lisa; Kuhn, Rudi B.; Moses Mogotsi, K.; Hellier, Coel; Angus, Ruth; Hattori, Soichiro; Chontos, Ashley; Ricker, George R.; Jenkins, Jon M.; Tenenbaum, Peter; Latham, David W.; Seager, Sara; Vanderspek, Roland K.; Winn, Joshua N.; Stockdale, Chris; Cloutier, Ryan
The Giants pipeline accesses TESS data, produces noise-corrected light curves, and searches for planets transiting evolved stars. Built with Lightkurve (ascl:1812.013) and written in Python, its emphasis is on finding giant planets around subgiant and RGB stars in TESS Full Frame Images (FFIs). Giants produces a one-page PDF summary for each target.
[ascl:1910.010] PEXO: Precise EXOplanetology
Feng, Fabo; Lisogorskyi, Maksym; Jones, Hugh R. A.; Kopeikin, Sergei M.; Butler, R. Paul; Anglada-Escude, Guillem; Boss, Alan P.
PEXO provides a global modeling framework for ns timing, μas astrometry, and μm/s radial velocities. It can account for binary motion and stellar reflex motions induced by planetary companions and also treat various relativistic effects both in the Solar System and in the target system (Roemer, Shapiro, and Einstein delays). PEXO is able to model timing to a precision of 1 ns, astrometry to a precision of 1 μas, and radial velocity to a precision of 1 μm/s.
