ROSE (Red-giant Oscillations Spectra Estimator): A Modular Machine-Learning Framework for Automated Asteroseismic Characterisation. I. and from TESS
Nipun Ghanghas, Dinil B. Palakkatharappil, Rafael A. Garcia +1
Space-based photometry from Kepler and TESS has delivered oscillation spectra for hundreds of thousands of red giants, and PLATO and the Roman Galactic Bulge Time-Domain Survey wil…
Multiple regular frequency spacings in Scuti stars from automated analysis of TESS oscillation spectra
Shravan M. Hanasoge, Shashwat Chamoli, Subrata Kumar Panda +1
The oscillation spectra of rapidly rotating Scuti stars are difficult to interpret because rotation modifies both the frequencies and spatial structure of the modes. Although t…
Stellar flare detection and characterization in ZTF High-cadence light curves
Aratrika Ghosh, Shravan Hanasoge, Matthew J. Graham +1
Stellar flares are brief, intense increases in brightness resulting from magnetic reconnection events in stellar atmospheres. In this paper, we have developed a pipeline to detect…
Period spacings and global seismic parameters for K2 red giants using deep learning
Nipun Ghanghas, Siddharth Dhanpal, Shravan Hanasoge +2
Gravity-mode period spacings (DPi_1) of red giants probe the stellar core directly, constraining its structure, mass and evolutionary state. Their measurement requires resolving na…
Potential of Gaia XP Spectra in Red Giant Star Asteroseismology: A Deep-Learning Approach
Rajarshi Barman, Shatanik Bhattacharya, Shravan M. Hanasoge +1
Red giants are tracers of stellar evolution & Galactic structure & their asteroseismic properties, particularly large frequency separation, frequency of maximum oscillation power &…
Machine Learning for Radial Velocity Analysis I: Vision Transformers as a Robust Alternative for Detecting Planetary Candidates
Anoop Gavankar, Tanish Mittal, Joe Ninan +1
Extreme precision radial velocity (EPRV) surveys usually require extensive observational baselines to confirm planetary candidates, making them resource-intensive. Traditionally, p…
