Slow Neutron-Capture Process: Low-Mass Asymptotic Giant Branch Stars and Presolar Silicon Carbide Grains [PDF]

Universe, 2022
Presolar grains are microscopic dust grains that formed in the stellar winds or explosions of ancient stars that died before the formation of the solar system.

Stellar flares

Living Reviews in Solar Physics
Magnetic storms on stars manifest as remarkable, randomly occurring changes of the luminosity over durations that are tiny in comparison to the normal evolution of stars.

Solar-Like Oscillators in the Kepler Era: A Review

Frontiers in Astronomy and Space Sciences, 2021
Many late-type stars across the Milky Way exhibit observable pulsations similar to our Sun that open up a window into stellar interiors. The NASA Kepler mission, a space-based photometric telescope, measured the micro-magnitude luminosity fluctuations ...

Black Hole Science With the Laser Interferometer Space Antenna

Frontiers in Astronomy and Space Sciences, 2021
The author reviews the scientific potential of the Laser Interferometer Space Antenna (LISA), a space-borne gravitational wave (GW) observatory to be launched in the early 30s. Thanks to its sensitivity in the milli-Hz frequency range, LISA will reveal a

Role of the Solar Minimum in the Waiting Time Distribution Throughout the Heliosphere

Geophysical Research Letters, 2021
Many processes throughout the heliosphere such as flares, coronal mass ejections (CMEs), storms and substorms have abrupt onsets. The waiting time between these onsets provides key insights as to the underlying dynamical processes. We explore the tail of

Solar evolution and extrema: current state of understanding of long-term solar variability and its planetary impacts

Progress in Earth and Planetary Science, 2021
The activity of stars such as the Sun varies over timescales ranging from the very short to the very long—stellar and planetary evolutionary timescales.

Unveiling the Structure and Dynamics of Red Giants With Asteroseismology

Frontiers in Astronomy and Space Sciences, 2020
The Kepler mission observed many thousands of red giants. The long time series, some as long as the mission itself, have allowed us to study red giants with unprecedented detail. Given that red giants are intrinsically luminous, and hence can be observed

The PANDORA project: an experimental setup for measuring in-plasma β-decays of astrophysical interest [PDF]

EPJ Web of Conferences, 2020
Experiments performed on Storage Rings have shown that lifetimes of beta-radionuclides can change dramatically as a function of theionization state. PANDORA (Plasmas for Astrophysics, Nuclear Decay Observation and Radiation for Archaeometry) aims at ...

Solar activity explored with new wavelet methods [PDF]

Annales Geophysicae, 2005
In order to improve the forecasts of the impact of solar activity on the terrestrial environment on time scales longer than days, improved understanding and forecasts of the solar activity are needed.
