The NuGrid AGB Evolution and Nucleosynthesis Data Set
Umberto Battino, Marco Pignatari, Ashley Tattersall +2
Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as…
Impact of newly measured 26Al(n, p)26Mg and 26Al(n, α)23Na reaction rates on the nucleosynthesis of 26Al in stars
Umberto Battino, Claudia Lederer-Woods, Marco Pignatari +6
The cosmic production of the short-lived radioactive nuclide 26Al is crucial for our understanding of the evolution of stars and galaxies. However, simulations of the stellar sites…
The s Process and Beyond
Maria Lugaro, Marco Pignatari, René Reifarth +1
Neutron captures produce the vast majority of abundances of elements heavier than iron in the Universe. Beyond the classical slow (s) and rapid (r) processes, there is observationa…
Improved thermonuclear rate of Ti(,)V and its astrophysical implication in rp-process
S. Q. Hou, C. Iliadis, M. Pignatari +4
Accurate Ti(,)V reaction rates are crucial for understanding the nucleosynthesis path of the rapid capture process (rp-process) that occurs in X-ray bursts. We…
PENELLOPE V. The magnetospheric structure and the accretion variability of the classical T Tauri star HM Lup
A. Armeni, B. Stelzer, R. A. B. Claes +9
HM Lup is a young M-type star that accretes material from a circumstellar disk through a magnetosphere. Our aim is to study the inner disk structure of HM Lup and to characterize i…
A trio of month long flares in the nova-like variable V704 And
Gabriella Zsidi, C. J. Nixon, T. Naylor +2
We present the discovery of an unusual set of flares in the nova-like variable V704 And. Using data from AAVSO, ASAS-SN, and ZTF, of the nova-like variable V704 And, we have discov…
A high HDO/HO ratio in the Class I protostar L1551 IRS5
Audrey Andreu, Audrey Coutens, Fernando Cruz-Sáenz de Miera +4
Water is a very abundant molecule in star-forming regions. Its deuterium fractionation is an important tool for understanding its formation and evolution during the star and planet…
Toward more accurate RR Lyrae metallicities
Geza Kovacs, Johanna Jurcsik
By using a large sample of published spectroscopic iron abundances, we point out the importance of gravity correction in deriving more accurate metal abundances for RR Lyrae stars.…
To Grow Old and Peculiar: A Survey of Anomalous Variable Stars in M80 and Age Determination using K2 and Gaia
László Molnár, Emese Plachy, Attila Bódi +11
The globular cluster Messier 80 was monitored by the Kepler space telescope for 80 days during the K2 mission. Continuous, high-precision photometry of such an old, compact cluster…
Brightness and mass accretion rate evolution during the 2022 burst of EX~Lupi
F. Cruz-Sáenz de Miera, Á. Kóspál, P. Ábrahám +18
EX Lupi is the prototype by which EXor-type outbursts were defined. It has experienced multiple accretion-related bursts and outbursts throughout the last decades, whose study have…
The Radial Distribution and Excitation of H2 around Young Stars in the HST-ULLYSES Survey
Kevin France, Nicole Arulanantham, Erin Maloney +8
The spatial distribution and evolution of gas in the inner 10 au of protoplanetary disks form the basis for estimating the initial conditions of planet formation. Among the most im…
The Gaia alerted fading of the FUor-type star Gaia21elv
Zsófia Nagy, Sunkyung Park, Péter Ábrahám +26
FU Orionis objects (FUors) are eruptive young stars, which exhibit outbursts that last from decades to a century. Due to the duration of their outbursts, and to the fact that only…
Testing ultralow amplitude Cepheid candidates in the Galactic disk by TESS and Gaia
Dóra Tarczay-Nehéz, László Molnár, Attila Bódi +1
Ultralow amplitude (ULA) and strange mode Cepheids are thought to be pulsating variable stars that are near to or are at the edges of the classical instability strip. Until now, a…
The -process nucleosynthesis in core-collapse supernovae. I. A novel analysis of -process yields in massive stars
L. Roberti, M. Pignatari, A. Psaltis +4
The -process nucleosynthesis in core-collapse supernovae is generally accepted as a feasible process for the synthesis of neutron-deficient isotopes beyond iron. However, crucia…
PENELLOPE IV. A comparison between optical forbidden lines and UV lines in the Orion OB1b and -Ori associations
M. Gangi, B. Nisini, C. F. Manara +17
Observing the spatial distribution and excitation processes of atomic and molecular gas in the inner regions (< 20 au) of young (< 10 Myr) protoplanetary disks helps us to understa…
