New constraints on the binary system HD 327083 and its gaseous and dusty environments
L. Cidale, P. Marchiano, M. Kraus +11
Binary systems with circumbinary molecular and dust rings are of great interest because they provide insights into the dynamics and evolution of stellar systems and the chemistry o…
PKS 2155-304: Long-Term Optical Photometric Monitoring and Variability Analysis
J. L. Weiss, I. Andruchow, E. J. Marchesini +6
Through the detailed study of the optical flux behaviour in blazars over time, it is possible to infer the conditions responsible for their observed emission. PKS 2155-304, a BL La…
Black holes in a bouncing universe
Iara Pintos, Daniela Pérez, Florencia L. Vieyro
Bouncing cosmologies offer an alternative to the standard CDM model by avoiding the problem of the initial cosmological singularity by construction. In these models, the univers…
Systematic study of the morphology and length of slow stable hybrid star branches
Mauro Mariani, Milva G. Orsaria, Germán Lugones +1
We introduce and systematically study the length of the slow stable hybrid star branch as a quantitative measure of the extended stability region that arises in hybrid neutron star…
Magneto-Gravitational Regulated Streamer Accretion onto a Class 0 Protostellar System
Bo Huang, Josep M. Girart, Ian W. Stephens +17
How do magnetic fields shape the way young stars gather gas from their birth clouds? Using high-resolution Atacama Large Millimeter/submillimeter Array observations of a young trip…
Multi epoch spectroscopic variability of the B supergiant HD75149
J. Chamoun-Contreras, C. Arcos, N. Machuca +6
Massive stars continuously enrich the surrounding interstellar medium by supplying it with stellar material driven by their powerful winds. B supergiant stars (BSGs) in particular…
