Cyclotron emitting magnetic white dwarfs in post common envelope binaries discovered with the Zwicky Transient Facility
J. van Roestel, A. C. Rodriguez, P. Szkody +20
We present the discovery of 14 new (and recovery of 4 known) low accretion rate magnetic white dwarfs in post-common envelope binaries that emit strong cyclotron emission using the…
ALMA detections of circumstellar disks in the giant Hii region M17. Probing the intermediate- to high-mass pre-main-sequence population
J. Poorta, M. Hogerheijde, A. de Koter +8
Our current understanding is that intermediate- to high-mass stars form in a way similar to low-mass stars, that is, through disk accretion. However, the physical conditions that p…
Spectroscopic observations of flares and superflares on AU Mic
P. Odert, M. Leitzinger, R. Greimel +13
The young active flare star AU~Mic is the planet host star with the highest flare rate from TESS data. Therefore, it represents an ideal target for dedicated ground-based monitorin…
On the non-dissipative orbital evolution of a binary system comprising non-compact components with misaligned spin and orbital angular momenta
Y. A. Lazovik, P. B. Ivanov, J. C. B. Papaloizou
In this Paper we determine the non-dissipative tidal evolution of a close binary system with an arbitrary eccentricity in which the spin angular momenta of both components are misa…
Long term UBV RI photometric and spectral monitoring of nova KT Eri during 2009-2023
S. Yu. Shugarov, P. Yu. Golysheva, S. Dallaporta +1
We present a status report of our intensive and long-term UBV RI photometric monitoring of nova KT Eri since its outbust in 2009. The old-nova in quiescence is characterized by ver…
Unequivocal detection of the tidal deformation of a red giant in a binary system via interferometry
Jaroslav Merc, Henri M. J. Boffin
While mass transfer in binary systems is a crucial aspect of binary evolution models, it remains far from understood. HD 352 is a spectroscopic binary exhibiting ellipsoidal variab…
Two waves of massive stars running away from the young cluster R136
Mitchel Stoop, Alex de Koter, Lex Kaper +10
Massive stars are predominantly born in stellar associations or clusters. Their radiation fields, stellar winds, and supernovae strongly impact their local environment. In the firs…
BH-BH mergers with & without EM counterpart: A model for stable tertiary mass transfer in hierarchical triple systems
F. Kummer, S. Toonen, A. Dorozsmai +2
Triple stars are prevalent within the population of observed stars. Their evolution, compared to binaries, is notably more complex, influenced by unique dynamical, tidal, and mass…
Hertzsprung gap stars in nearby galaxies and the Quest for Luminous Red Novae Progenitors
Hugo Tranin, Nadejda Blagorodnova, Viraj Karambelkar +5
After the main sequence phase, stars more massive than 2.5 M rapidly evolve through the Hertzsprung gap as yellow giants and supergiants (YSG), before settling into the red…
Impact of HI cooling and study of accretion disks in AGB wind-companion smoothed particle hydrodynamic simulations
Jolien Malfait, Lionel Siess, Mats Esseldeurs +4
High-resolution observations reveal that the outflows of evolved low- and intermediate-mass stars harbour complex morphological structures that are linked to the presence of one or…
Flare heating of the chromosphere: Observations of flare continuum from GREGOR and IRIS
M. García-Rivas, J. Kašparová, A. Berlicki +8
Context: On 2022 May 4, an M5.7 flare erupted in the active region NOAA 13004, which was the target of a coordinated campaign between GREGOR, IRIS, Hinode, and ground-based instrum…
Comment on Ádám et al. (2023): Large fraction of already known systems reported
P. Zasche
In this work, I report that large fraction of stars detected by Ádám et al. (2023, A&A, 674, A170, arXiv:2304.08394) and noted in that work as new discoveries are in fact known sys…
Testing volume integrals of travel-time sensitivity kernels for flows
Michal Svanda, Daniel Chmurny
Context: Helioseismic inversions rely largely on sensitivity kernels, 3-D spatial functions describing how do the changes in the solar interior translate into the changes of helios…
A spectroscopic and kinematic survey of fast hot subdwarfs
S. Geier, U. Heber, A. Irrgang +19
Hot subdwarfs (sdO/B) are the stripped helium cores of red giants formed by binary interactions. Close hot subdwarf binaries with massive white dwarf companions have been proposed…
X-Shooting ULLYSES: Massive Stars at low metallicity VIII. Stellar and wind parameters of newly revealed stripped stars in Be binaries
V. Ramachandran, A. A. C. Sander, D. Pauli +16
On the route towards merging neutron stars and stripped-envelope supernovae, binary population synthesis predicts a large number of post-interaction systems with massive stars that…
The jet of BP Tau
A. V. Dodin, S. A. Potanin, M. A. Burlak +6
A strong global magnetic field of young low-mass stars and a high accretion rate are the necessary conditions for the formation of collimated outflows (jets) from these objects. Bu…
The dependence of the magnetism of a near-limb sunspot on height
M. Benko, H. Balthasar, P. Gömöry +2
The physical parameters of the sunspot are not fully understood, especially the height dependence of the magnetic field. So far, it is also an open question as to which heights the…
Gaia23ckh: Symbiotic outburst of the assumed Mira variable V390 Sco
Jaroslav Merc, Peter Velez, Stéphane Charbonnel +5
The poorly studied variable star V390 Sco, previously classified as a Mira pulsator, was detected in a brightening event by the ESA Gaia satellite in September 2023. This work pres…
A Universal Method for Solar Filament Detection from H-alpha Observations using Semi-supervised Deep Learning
Andrea Diercke, Robert Jarolim, Christoph Kuckein +7
Filaments are omnipresent features in the solar atmosphere. Their location, properties and time evolution can provide information about changes in solar activity and assist the ope…
RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99
Evan Butler, Andrea Kunder, Zdenek Prudil +16
Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination.…
