Probability of Undetected Brown Dwarfs Near Sun

Published:Dec 30, 2025 16:17

ArXiv

Analysis

This paper investigates the likelihood of undetected brown dwarfs existing in the solar vicinity. It uses observational data and statistical analysis to estimate the probability of finding such an object within a certain distance from the Sun. The study's significance lies in its potential to revise our understanding of the local stellar population and the prevalence of brown dwarfs, which are difficult to detect due to their faintness. The paper also discusses the reasons for non-detection and the possibility of multiple brown dwarfs.
Reference

“With a probability of about 0.5, there exists a brown dwarf in the immediate solar vicinity (< 1.2 pc).”

Bright Type Iax Supernova SN 2022eyw Analyzed

ArXiv

Analysis

This paper provides detailed observations and analysis of a bright Type Iax supernova, SN 2022eyw. It contributes to our understanding of the explosion mechanisms of these supernovae, which are thought to be caused by the partial deflagration of white dwarfs. The study uses photometric and spectroscopic data, along with spectral modeling, to determine properties like the mass of synthesized nickel, ejecta mass, and kinetic energy. The findings support the pure deflagration model for luminous Iax supernovae.
Reference

“The bolometric light curve indicates a synthesized $^{56}$Ni mass of $0.120\pm0.003~ ext{M}_{\odot}$, with an estimated ejecta mass of $0.79\pm0.09~ ext{M}_{\odot}$ and kinetic energy of $0.19 imes10^{51}$ erg.”

Predicting the detection yields of giant planets and brown dwarfs with CSST astrometry

Published:Dec 29, 2025 11:18
1 min read
ArXiv

Analysis

This article likely discusses a research paper that uses astrometry data from the Chinese Space Station Telescope (CSST) to predict the number of giant planets and brown dwarfs that can be detected. The focus is on the expected detection yields, which is a key metric for evaluating the telescope's capabilities in exoplanet and brown dwarf surveys. The research likely involves simulations and modeling to estimate the number of these objects that CSST will be able to find.
