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.…
Peering into the central region of a nano-quasar: XMM-Newton and Chandra views of the CH Cyg Symbiotic System
J. A. Toalá, O. González-Martín, M. Karovska +3
We present the analysis of archival XMM-Newton and Chandra observations of CH Cyg, one of the most studied symbiotic stars (SySts). The combination of the high-resolution XMM-Newto…
Dissecting the Extended X-ray Emission in the Merging Pair NGC 6240
A. Paggi, G. Fabbiano, E. Nardini +3
We present a detailed spectral and imaging analysis of the central radius () region of the merger galaxy NGC 6240 that makes use of all the available \…
The expanding bipolar shell of the helium nova V445 Puppis
P. A. Woudt, D. Steeghs, M. Karovska +8
From multi-epoch adaptive optics imaging and integral field unit spectroscopy we report the discovery of an expanding and narrowly confined bipolar shell surrounding the helium nov…
Cepheid Limb Darkening Models for the VLTI
Massimo Marengo, Margarita Karovska, Dimitar D. Sasselov +3
We present a new method to compute wavelength- and phase-dependent limb darkening corrections for classical Cepheids. These corrections are derived from hydrodynamic simulations an…
