MSSPE: Multi-Source Stellar Parameter Estimation under Incomplete Photometric Conditions

The Astronomical Journal
Accurate determination of stellar parameters is fundamental to astrophysical research, as it underpins our understanding of stellar evolution and characteristics. Most existing studies rely primarily on spectroscopic observations, which typically provide

Data Analysis and Simulations of the Large Data Sets in the Galactic Astronomy

, 2011
In the last decades large data sets covering a wide range of both resolution and observed regions have been accumulated in the Astronomy. Follow-up technology involving the storage and the access to these data is also necessary to develop methods and tools that will allow their usage. In this chapter, I will review the use of the large data sets in the

Contour Analysis Tool: An Interactive Tool for Background and Morphology Analysis

The Astrophysical Journal
We introduce the Contour Analysis Tool (CAT), a Python toolkit aimed at identifying and analyzing structural elements in density maps. CAT employs various contouring techniques, including the lowest-closed contour, linear and logarithmic Otsu ...

A multimodal approach to data analysis in astronomy: sonouno applications in photometry and spectroscopy

RAS Techniques and Instruments
ABSTRACT In the past decade, multimodal data analysis has gained importance, especially for including individuals with visual impairments in education and science dissemination. However, its application in scientific research is still limited due to a lack of conclusive evidence on its robustness and performance.

A Novel Convolutional Neural Network–Long Short-term Memory Model for Interplanetary Coronal Mass Ejection Detection

The Astrophysical Journal Supplement Series
Current models for detecting interplanetary coronal mass ejections (ICMEs) using spacecraft in situ measurements rely heavily on manual processes, resulting in time-consuming procedures, inconsistencies in identification criteria, and gaps in existing ...
