| - text: Solar Observations by Angelo Secchi. I. Digitization of Original Documents |
| and Analysis of Group Numbers over the Period of 1853-1878. Angelo Secchi, an |
| Italian Jesuit and prominent scientist of the 19th century, and one of the founders |
| of modern astrophysics, observed the Sun regularly at the Collegio Romano in Rome, |
| Italy, for more than 25 yr. Results from his observations are reported in articles |
| published in the scientific journals of the time, as well as in drawings and personal |
| notebooks that are stored in the historical archive of the Istituto Nazionale |
| di Astrofisica Osservatorio Astronomico di Roma. The latter material, which reports |
| solar observations performed from 1853-1878, includes original documents from |
| Secchi and from a few of his close collaborators. The above unique material has |
| recently been digitized for preservation purposes and for allowing the scientific |
| exploitation of data not easily accessible so far. A total of more than 5400 digital |
| images have been produced. Here we present the archival material and the new digital |
| data derived from it. We also present results obtained from our primary analysis |
| of the new digital data. In particular, we produced new measurements of the group |
| number from 1853-1878, which will be available for future recalibration of the |
| group number series. |

| - text: 'Disk-resolved Photometric Properties of Pluto and the Coloring Materials |
| across its Surface. A multiwavelength regionally dependent photometric analysis |
| of Pluto''s anti-Charon-facing hemisphere using images collected by New Horizons'' |
| Multispectral Visible Imaging Camera (MVIC) reveals large variations in the absolute |
| value and spectral slope of the single-scattering albedo. Four regions of interest |
| are analyzed: the dark equatorial belt, Pluto''s north pole, nitrogen-rich regions, |
| and the mid-latitude terrains. Regions dominated by volatile ices such as Lowell |
| Regio and Sputnik Planitia present single-scattering albedos of ∼0.98 at 492 nm, |
| almost neutral across MVIC''s visible wavelength range (400-910 nm), indicating |
| limited contributions from tholin materials. Pluto''s dark equatorial regions, |
| informally named Cthulhu and Krun Maculae, have single-scattering albedos of ∼0.16 |
| at 492 nm and are the reddest regions. Applying the Hapke radiative transfer model |
| to combined MVIC and Linear Etalon Imaging Spectral Array (LEISA) spectra (400-2500 |
| nm) of Cthulhu Macula and Lowell Regio successfully reproduces the spectral properties |
| of these two regions of dramatically disparate coloration, composition, and morphology. |
| Since this model uses only a single coloring agent, very similar to the Titan-like |
| tholin of Khare et al., to account for all of Pluto''s colors, this result supports |
| the Grundy et al. conclusion that Pluto''s coloration is the result of photochemical |
| products mostly produced in the atmosphere. Although cosmic rays and extreme ultraviolet |
| photons reach Pluto''s surface where they can drive chemical processing, observations |
| of diverse surface colors do not require different chemical products produced |
| in different environments. We report a correction scaling factor in the LEISA |
| radiometric calibration of 0.74 ± 0.05.' |

| # KAILAS |
| KAILAS (aka Keyword Labeler At SciX aka Indus-UAT-Labeler aka nasa-smd-ibm-v0.1_UAT_Labeler) is a RoBERTa-based, Encoder-only transformer model, domain-adapted for NASA Science Mission Directorate (SMD) applications. It's fine-tuned on scientific journals and articles relevant to NASA SMD, aiming to enhance natural language technologies like information retrieval and intelligent search. |
| This specific fork was finetuned on SciX Digital Library (https://scixplorer.org/, formerly NASA-ADS) proprietary data to label text with UAT labels (https://astrothesaurus.org/) |
