Evolved stars, multiplicity and planets: Shaping and Being Shaped by Stellar Evolution
Theo Khouri, Wouter Vlemmings, Elvire De Beck +21
Understanding how planets and stellar companions survive and interact with their host stars as they evolve, or are ultimately destroyed in the process, is essential both for predic…
ALMA's sharpest view of IRAS 08544-4431: Unveiling the dust distribution asymmetries in the circumbinary disk
Maksym Mohorian, Devika Kamath, Elizabeth Cappellazzo +10
The interactions between post-asymptotic giant branch (post-AGB) binaries and their circumbinary disks play a central role in shaping the evolution of these systems. Circumbinary d…
Photospheric Chemical Depletion in Post-AGB/Post-RGB Binaries with Second-Generation Protoplanetary Discs
Maksym Mohorian
The origin and evolution of chemical elements in the Universe are governed not only by nucleosynthesis processes in stars, but also by mechanisms that alter observed photospheric c…
Abundance Analysis of Chemically Depleted Post-AGB/Post-RGB Binaries with Faint Discs
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Post-AGB and post-RGB binaries with stable circumbinary discs provide key insights into late stellar and disc evolution, revealing how binary interactions shape disc structure and…
s-process Enriched Post-AGB Star J003643.94-723722.1 in the SMC with an Extreme C/O Ratio and the First Precise Detection of Lead
Meghna Menon, Devika Kamath, Maksym Mohorian +6
Post-asymptotic giant branch (post-AGB) stars are exquisite tracers of s-process nucleosynthesis via their surface abundances. We present a comprehensive analysis of J003643.947…
Deterministic and Stochastic Study of the X-ray Emission from the TeV Blazar Mrk~421
Radim Pánis, Gopal Bhatta, Tek P. Adhikari +6
We present a comprehensive timing analysis of X-ray data from the {\it XMM-Newton} satellite, examining 50 light curves covering 17 years of observations of the blazar Mrk~421. Thi…
Tracing Chemical Depletion in Evolved Binaries Hosting Second-Generation Transition Discs
Maksym Mohorian, Devika Kamath, Meghna Menon +4
The mechanisms responsible for chemical depletion across diverse astrophysical environments are not yet fully understood. In this paper, we investigate chemical depletion in post-A…
Probing X-ray Timing and Spectral Variability in the Blazar PKS 2155-304 Over a Decade of XMM-Newton Observations
Gopal Bhatta, Suvas C. Chaudhary, Niraj Dhital +5
Blazars, a class of active galactic nuclei (AGN) powered by supermassive black holes, are known for their remarkable variability across multiple timescales and wavelengths. Despite…
s-process Enriched Evolved Binaries in the Galaxy and the Magellanic Clouds
Meghna Menon, Devika Kamath, Maksym Mohorian +2
Post-asymptotic giant branch stars (post-AGB) in binary systems, with typical orbital periods between ~100 to ~1000 days, result from a poorly understood interaction that terminate…
The first measurements of carbon isotopic ratios in post-RGB stars: SZ Mon and DF Cyg. E-iSpec: A spectral analysis tool to derive elemental abundances and isotopic ratios for evolved stars
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Dusty post-red giant branch (post-RGB) stars are low- and intermediate-mass stars where the RGB evolution was prematurely terminated by a poorly understood binary interaction. Thes…
Constraining X-ray variability of the blazar 3C 273 using XMM-Newton observations over two decades
Adithiya Dinesh, Gopal Bhatta, Tek P. Adhikari +5
Blazars exhibit relentless variability across diverse spatial and temporal frequencies. The study of long- and short-term variability properties observed in the X-ray band provides…
X-ray timing and spectral variability properties of blazars S5 0716+714, OJ 287, Mrk 501, and RBS 2070
Maksym Mohorian, Gopal Bhatta, Tek P. Adhikari +6
The X-ray emission from blazars has been widely investigated using several space telescopes. In this work, we explored statistical properties of the X-ray variability in the blazar…
Luminosities and masses of single Galactic Post-Asymptotic Giant Branch (Post-AGB) stars with distances from EDR3: The revelation of an -process diversity
Devika Kamath, Hans Van Winckel, Paolo Ventura +4
Post-AGB stars are exquisite probes of AGB nucleosynthesis. However, the previous lack of accurate distances jeopardised comparison with theoretical AGB models. The Early Da…
Hard X-ray properties of NuSTAR blazars
Gopal Bhatta, Maksym Mohorian, Illya Bilinsky
Context. Investigation of the hard X-ray emission properties of blazars is key to the understanding of the central engine of the sources and associated jet process. In particular,…
