He I λ 10 830 Å in the transmission spectrum of HD209458 b
Context. Recently, the He I triplet at 10 830 Å was rediscovered as an excellent probe of the extended and possibly evaporating atmospheres of close-in...
HE-LHC: The High-Energy Large Hadron Collider. Future Circular Collider Conceptual Design Report Volume 4
In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide...
Heat transfer in sunspot penumbrae. Origin of dark-cored penumbral filaments
Context: Observations at 0.1 arcsec have revealed the existence of dark cores in the bright filaments of sunspot penumbrae. Expectations are high that such dark...
Heating of the Magnetized Solar Chromosphere by Partial Ionization Effects
In this paper, we study the heating of the magnetized solar chromosphere induced by the large fraction of neutral atoms present in this layer. The presence of...
Heating of the Partially Ionized Solar Chromosphere by Waves in Magnetic Structures
In this paper, we show a “proof of concept” of the heating mechanism of the solar chromosphere due to wave dissipation caused by the effects of partial...
Heavy Element Nucleosynthesis in the Brightest Galactic Asymptotic Giant Branch Stars
We present updated calculations of stellar evolutionary sequences and detailed nucleosynthesis predictions for the brightest asymptotic giant branch (AGB) stars...
Heavy-element Abundances in P-rich Stars: A New Site for the s-process?
The recently discovered phosphorus-rich stars pose a challenge to stellar evolution and nucleosynthesis theory, as none of the existing models can explain their...
Heavy-element production in a compact object merger observed by JWST
The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the...
Heavy-element yields and abundances of asymptotic giant branch models with a Small Magellanic Cloud metallicity
We present new theoretical stellar yields and surface abundances for asymptotic giant branch (AGB) models with a metallicity appropriate for stars in the Small...
