Evolution of eccentric high-mass X-ray binaries. The case of GX 301-2
A. Simaz Bunzel, F. García, J. A. Combi +1
The formation of neutron stars is associated with powerful astrophysical transients such as supernovae. In many cases, asymmetries in the supernova explosions are thought to be res…
Evidence of structural discontinuities in the inner core of red-giant stars
Mathieu Vrard, Margarida S. Cunha, Diego Bossini +3
Red giants are stars in the late stages of stellar evolution. Because they have exhausted the supply of hydrogen in their core, they burn the hydrogen in the surrounding shell. Onc…
Impact of tides on non-coplanar orbits of progenitors of high-mass X-ray binaries
A. Simaz Bunzel, F. García, J. A. Combi +2
An important stage in the evolution of massive binaries is the formation of a compact object in the system. It is believed that in some cases a momentum kick is imparted to the new…
MINDS. The detection of CO with JWST-MIRI indicates abundant CO in a protoplanetary disk
Sierra L. Grant, Ewine F. van Dishoeck, Benoît Tabone +43
We present JWST-MIRI MRS spectra of the protoplanetary disk around the low-mass T Tauri star GW Lup from the MIRI mid-INfrared Disk Survey (MINDS) GTO program. Emission from $^{12}…
Extreme-Ultraviolet Wave and Accompanying Loop Oscillations
Pooja Devi, Ramesh Chandra, Arun Kumar Awasthi +2
We present the observations of an extreme-ultraviolet (EUV) wave, which originated from the active region (AR) NOAA 12887 on 28 October 2021 and its impact on neighbouring loops. T…
Ultracool dwarfs in Gaia DR3
L. M. Sarro, A. Berihuete, R. L. Smart +36
Aims. In this work we use the Gaia DR3 set of ultracool dwarf candidates and complement the Gaia spectrophotometry with additional photometry in order to characterise its global pr…
