Characterizing bright Scuti pulsators using TESS light curves:II. Pulsation amplitude and energy distributions
Prasad Mani, Timothy Bedding, Simon Murphy +2
Pulsations in Scuti stars exhibit a wide range of excited frequencies and amplitudes, but the underlying principles governing their amplitude distribution remain unclear. We re…
Ejecta clumps revealed by study of reverse-shocked ejecta through MUSE integral field spectroscopy of SNR 0509-67.5
Priyam Das, Ivo Seitenzahl, J. Martin Laming +3
We report the discovery of a spatially resolved clumpy ejecta structure in the reverse-shocked ejecta of SNR 0509-67.5, revealed through multiple faint and broad forbidden coronal…
Deep MUSE observations of SNR 0509-67.5 reveal a double degenerate merger progenitor
Priyam Das, Ivo R. Seitenzahl, Gilles Ferrand +5
Deep MUSE observations of SNR 0509-67.5 reveal that the coronal [Fe\,\textsc{xiv}] 5303 emission line appears with either one or two velocity components across the entire…
The Scuti pulsator occurrence as a function of age, , rotation, and metallicity
Ian Berry, Daniel Huber, Yaguang Li +3
Many A- and F- type stars do not display Scuti pulsations, despite being located within the instability strip. We use photometry from the TESS Mission to discover and study …
Population synthesis of delta Scuti stars: the instability strip, period-luminosity relation, and large-separation distribution
Simon J. Murphy, Anuj Gautam
Interpreting the observed properties of intermediate-mass stars requires accounting for rotation, binarity, intrinsic population diversity, and measurement uncertainty. We combine…
Wildly Oscillating Stars -- Unexplained dense ridge-like frequency agglomerations in A and F type pulsators
V. Antoci, J. Labadie-Bartz, M. Swiech +14
We investigate the origin of the dense, ridge-like frequency clusters observed in a subset of A and F type pulsating stars, which we refer to as `wildly oscillating' stars (WOS). T…
Helium emission from Balmer-dominated shocks in Type Ia supernova remnants provides constraints to their progenitor systems
Priyam Das, Ivo Rolf Seitenzahl, Parviz Ghavamian +4
Balmer-dominated shocks in Type Ia supernova remnants offer powerful probes into collisionless shock physics and hints towards supernova progenitor environments. Prior studies focu…
