The impact of periastron passage on the X-ray and optical properties of the Symbiotic System R Aquarii
D. A. Vásquez-Torres, J. A. Toalá, A. Sacchi +4
Multi-epoch Chandra and XMM-Newton observations of the symbiotic system R Aquarii (R Aqr) spanning 22 yr are analysed by means of a reflection model produced by an accretion disc.…
An Audit of the Light Curves of RV Tau Variable Stars in the ASAS-SN Database
Rachel N. Nere, Rodolfo Montez, Sophia Sánchez-Maes
RV Tauri variable stars are pulsating evolved stars that are identified by a characterizing feature in their light curves: alternating deep and shallow minima. Many RV Tauri variab…
Asymptotic giant branch stars in the eROSITA-DE eRASS1 catalog
Martin A. Guerrero, Rodolfo Montez, Roberto Ortiz +2
AGB stars are not expected to be X-ray-emitters, yet a small fraction of them, the so-called X-AGBs, show X-ray emission that can be attributed to coronal activity of a companion o…
ALMA Observations of Molecular Line Emission from High-excitation Bipolar Planetary Nebulae
Paula Moraga Baez, Joel H. Kastner, Jesse Bublitz +7
We present early results from our program of ALMA Band 6 (1.3mm) molecular line mapping of a sample of nearby, well-studied examples of high-excitation, bipolar/pinched-waist and m…
Discovery of Radial Spectral Hardening in the Hot Bubble of Planetary Nebula BD+30 3639 with Median Energy Imaging
Rodolfo Montez
We introduce a new imaging analysis technique to study the spatial distribution of the X-ray emission from the hot bubble of planetary nebula BD+30 3639. Hot bubble emission is typ…
Shocks and Photoionization of the Inner 650 AU Jet of the Interacting Binary Star R Aquarii from Multiwavelength Hubble Space Telescope Observations
Caroline D. Huang, Margarita Karovska, Warren Hack +3
Astrophysical jets are present in a range of environments, including young stellar objects, X-ray binaries, and active galactic nuclei, but their formation is still not fully under…
