Formation and Evolution of [Wolf-Rayet] Planetary Nebulae through a Late Thermal Pulse
J. B. RodrÃguez-González, R. Orozco-Duarte, J. A. Toalá +5
We present the first radiation-hydrodynamical simulations of the formation of a born-again planetary nebula (PN) triggered by a late thermal pulse (LTP). The 2D radiation-hydrodyna…
Wind accretion onto planets orbiting an evolving Solar-like star and their detectability
P. Padilla-López, R. F. Maldonado, J. A. Toalá +2
As stars evolve, they undergo significant changes in their physical properties, which can have a profound impact on the planets orbiting them. In particular, the mass lost through…
Accretion in Binary Systems with Slow Stellar Winds
Jesús A. Toalá, Emilio Tejeda, Diego A. Vasquez-Torres
Wind accretion in binary systems is commonly described using the Bondi-Hoyle-Lyttleton (BHL) formalism. However, its standard implementation fails in the slow-wind regime, where th…
SDSS-V Local Volume Mapper (LVM): Helix Nebula public data, Data Analysis Pipeline data products
S. F. Sánchez, J. E. Méndez-Delgado, A. MejÃa-Narváez +21
We present a spatially resolved spectroscopic analysis of the Helix Nebula (NGC 7293) using data from the SDSS-V Local Volume Mapper (LVM), by applying the recently developed LVM D…
Formation and X-ray emission from hot bubbles in planetary nebulae - III. The impact of [Wolf-Rayet]-type winds
Rogelio Orozco-Duarte, Jesús A. Toalá, S. Jane Arthur +3
We use radiation-hydrodynamical simulations to investigate the formation and synthetic X-ray emission of hot bubbles within planetary nebulae (PNe) driven by the powerful winds of…
A targeted radio survey of infrared-selected bow shock candidates
M. Moutzouri, J. Mackey, N. Castro +8
Bow shocks around massive stars have primarily been detected in IR emission, but radio detections are becoming more frequent with the commissioning of sensitive and large field-of-…
