[ascl:2412.027] mr-plotter: Mass-radius diagrams plotter
Castro-González, A.; Demangeon, O. D. S.; Lillo-Box, J.; Lovis, C.; Lavie, B.; Adibekyan, V.; Acuña, L.; Deleuil, M.; Aguichine, A.; Zapatero Osorio, M. R.; Tabernero, H. M.; Davoult, J.; Alibert, Y.; Santos, N.; Sousa, S. G.; Antoniadis-Karnavas, A.; Borsa, F.; Winn, J. N.; Allende Prieto, C.; Figueira, P.; Jenkins, J. M.; Sozzetti, A.; Damasso, M.; Silva, A. M.; Astudillo-Defru, N.; Barros, S. C. C.; Bonfils, X.; Cristiani, S.; Di Marcantonio, P.; González Hernández, J. I.; Curto, G. Lo; Martins, C. J. A. P.; Nunes, N. J.; Palle, E.; Pepe, F.; Seager, S.; Suárez Mascareño, A.
Mister plotter (mr-plotter) creates paper-quality mass-radius diagrams based on a wide range of state-of-the-art models of planetary interiors and atmospheres. It can be used to contextualize planets and infer their possible internal structures. It can also be used to search for correlations at a population level with its color-coding option based on any property collected in the NASA Exoplanet Archive, PlanetS, and Exoplanet.eu catalogs. mr-plotter can also produce article-ready two-column plots.
[ascl:2111.016] SteParSyn: Stellar atmospheric parameters using the spectral synthesis method
Tabernero, H. M.; Marfil, E.; Montes, D.; González Hernández, J. I.
SteParSyn infers stellar atmospheric parameters (Teff, log g, [Fe/H], and Vbroad) of FGKM-type stars using the spectral synthesis method. The code uses the MCMC sampler emcee (ascl:1303.002) in conjunction with an spectral emulator that can interpolate spectra down to a precision < 1%. A grid of synthetic spectra that allow the user to characterize the spectra of FGKM-type stars with parameters in the range of 3500 to 7000 K in Teff, 0.0 to 5.5 dex in log g, and −2.0 to 1.0 dex in [Fe/H] is also provided.
[ascl:1907.018] StePar: Inferring stellar atmospheric parameters using the EW method
Tabernero, H. M.; Marfil, E.; Montes, D.; González Hernández, J. I.
StePar computes the stellar atmospheric parameters Teff, log g, [Fe/H], and ξ of FGK-type stars using the Equivalent Width (EW) method. The code implements a grid of MARCS model atmospheres and uses the MOOG radiative transfer code (ascl:1202.009) and TAME (ascl:1503.003). StePar uses a Downhill Simplex minimization algorithm, running it twice for any given star, to compute the stellar atmospheric parameters.
[ascl:1804.017] APPHi: Automated Photometry Pipeline for High Cadence Large Volume Data
Sánchez, E.; Castro, J.; Silva, J.; Hernández, J.; Reyes, M.; Hernández, B.; Alvarez, F.; García, T.
APPHi (Automated Photometry Pipeline) carries out aperture and differential photometry of TAOS-II project data. It is computationally efficient and can be used also with other astronomical wide-field image data. APPHi works with large volumes of data and handles both FITS and HDF5 formats. Due the large number of stars that the software has to handle in an enormous number of frames, it is optimized to automatically find the best value for parameters to carry out the photometry, such as mask size for aperture, size of window for extraction of a single star, and the number of counts for the threshold for detecting a faint star. Although intended to work with TAOS-II data, APPHi can analyze any set of astronomical images and is a robust and versatile tool to performing stellar aperture and differential photometry.
