TL;DR
This paper presents seismic analysis results of four solar-like stars observed by Kepler over eight months, revealing oscillations in faint stars and advancing stellar astrophysics understanding.
Contribution
It provides the first detailed seismic analysis of four faint solar-like stars observed continuously for over eight months by Kepler.
Findings
Detection of oscillations in faint stars (magnitudes 10.5 to 12)
Extended observation period improves seismic data quality
Enhanced understanding of stellar oscillations in solar-like stars
Abstract
Having started science operations in May 2009, the Kepler photometer has been able to provide exquisite data of solar-like stars. Five out of the 42 stars observed continuously during the survey phase show evidence of oscillations, even though they are rather faint (magnitudes from 10.5 to 12). In this paper, we present an overview of the results of the seismic analysis of 4 of these stars observed during more than eight months.
