Asteroseismology of red giants & galactic archaeology

, 2017
Red-giant stars are low- to intermediate-mass ($M \lesssim 10$~M$_{\odot}$) stars that have exhausted hydrogen in the core. These extended, cool and hence red stars are key targets for stellar evolution studies as well as galactic studies for several ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Solar-like pulsating stars as distance indicators: G-K giants in the CoRoT and Kepler fields

EPJ Web of Conferences, 2012
The detection of radial and non-radial solar-like oscillations in thousands of G-K giants with CoRoT and Kepler is paving the road for detailed studies of stellar populations in the Galaxy.

Mixed-mode Ensemble Asteroseismology of Low-luminosity Kepler Red Giants

The Astrophysical Journal, 2023
We present measurements of the dipole mode asymptotic period spacing (ΔΠ _1 ), the coupling factor between the p - and g -modes ( q ), the g -mode phase offset ( ϵ _g ), and the mixed-mode frequency rotational splitting ( δ ν _rot ) for 1074 low ...

Masses of subgiant stars from asteroseismology using the coupling strengths of mixed modes

, 2012
Since few decades, asteroseismology, the study of stellar oscillations, enables us to probe the interiors of stars with great precision. It allows stringent tests of stellar models and can provide accurate radii, masses and ages for individual stars.

Visual Recovery Reflects Cortical MeCP2 Sensitivity in Rett Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Rett syndrome (RTT) is a devastating neurodevelopmental disorder with developmental regression affecting motor, sensory, and cognitive functions. Sensory disruptions contribute to the complex behavioral and cognitive difficulties and represent an important target for therapeutic interventions.

Wave topology of stellar inertial oscillations

Physical Review Research
Inertial waves in convective regions of stars exhibit topological properties linked to a Chern number of 1. The first of these is a unique, unidirectional, prograde oscillation mode within the cavity, which propagates at arbitrarily low frequencies for ...

CoRoT and Kepler results: Solar-like oscillators

, 2013
The space-borne observatories CoRoT (Convection Rotation and planetary Transits) and Kepler have provided photometric time series data of unprecedented precision for large numbers of stars.

Interleukin‐6 as a Key Biomarker in Facioscapulohumeral Dystrophy: Evidence From Longitudinal Analyses

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Facioscapulohumeral muscular dystrophy type 1 (FSHD1) is a progressive neuromuscular disorder with no approved treatments. Identifying reliable biomarkers is critical to monitor disease severity, activity, and progression. Interleukin‐6 (IL‐6) has been proposed as a candidate biomarker, but longitudinal validation is limited ...

High-order Gravity-mode Period Spacing Patterns of Intermediate-mass (1.5 M⊙ < M < 3 M⊙) Main-sequence Stars. I. Perturbative Analysis

The Astrophysical Journal
Theoretical study of the high-order gravity-mode period spacing (Δ P _g ) pattern is relevant to a better understanding of the internal properties of intermediate-mass (1.5 M _⊙
