Chang'e 7 Lunar Lander Optical Camera-Telescope: Optical Astronomy from the Moon
Quentin Andrew Parker, Partha Sarathi Pal, Junhao Chen +8
We report the design and manufacture of a new, lightweight, wide-field, optical camera-telescope on board the Chang'e 7 lunar mission (launched in August 2026 and due for lunar tou…
One cluster, two clusters, no cluster? -- The curious case of HSC 2686 and Lynga 3
Andreas Ritter, Quentin A. Parker, Xizhe Xie +1
This study was motivated by the search for Planetary Nebulae (PNe) and Open Cluster (OCs) associations. Only 5 PNe are currently in Galactic OCs among the previous OCs…
Planetary Nebulae in the eROSITA eRASS1 catalog
Haoyang Yuan, Martin A. Guerrero, Quentin Parker +1
Some planetary nebulae (PNe) host X-ray-emitting hot bubbles shaped by stellar wind interactions and/or harbor X-ray-emitting central stars due to accretion, shocks within their fa…
The secular evolution of planetary nebula IC 418 and its implications for carbon star formation
Albert A. Zijlstra, Quentin A. Parker
The rate of stellar evolution can rarely be measured in real time. The fastest evolution (excluding event-driven evolution), where stars may evolve measurably over decades, is duri…
Evaluation of the performance of a CdZnTe-based soft -ray detector for CubeSat payloads
Kees de Kuijper, Rishank Diwan, Partha Sarathi Pal +4
The low-energy -ray (0.1-30 MeV) sky has been relatively unexplored since the decommissioning of the COMPTEL instrument on the Compton Gamma-Ray Observatory (CGRO) satellite in…
From an amateur PN candidate to the Rosetta Stone of SN Iax research
Andreas Ritter, Quentin A. Parker, Foteini Lykou +3
On August 25th 2013 Dana Patchick from the "Deep Sky Hunters" (DSH) amateur astronomer group discovered a diffuse nebulosity in the Wide-field Infrared Survey Explorer (WISE) mid-I…
The curious case of II Lup: a complex morphology revealed with SAM/NACO and ALMA
Foteini Lykou, Albert A. Zijlstra, Jacques Kluska +5
We present the first-ever images of the circumstellar environment of the carbon-rich AGB star II Lup in the infrared and sub-mm wavelengths, and the discovery of the envelope's non…
A fast and portable Re-Implementation of Piskunov and Valenti's Optimal-Extraction Algorithm with improved Cosmic-Ray Removal and Optimal Sky Subtraction
A. Ritter, E. A. Hyde, Q. A. Parker
We present a fast and portable re-implementation of Piskunov and Valenti's optimal-extraction algorithm (Piskunov & Valenti, 2002} in C/C++ together with full uncertainty propagati…
Further investigation of white dwarfs in the open clusters NGC2287 and NGC3532
P. D. Dobbie, A. Day-Jones, K. A. Williams +5
We report the results of a CCD imaging survey, complimented by astrometric and spectroscopic follow-up studies, that aims to probe the fate of heavy-weight intermediate mass stars…
