Abstract We present starkiller , an open-source Python package for forward-modeling flux retrieval from integral field unit (IFU) spectrograph data cubes. simultaneously provides stellar spectral classification, relative velocity, and line-of-sight extinction all sources in a catalog, alongside source-subtracted cube. It performs synthetic difference imaging by simulating catalog the of view, using positions fluxes to scale models, independent This differencing method is particularly...
Context . Jupiter-family comets (JFCs), which originate from the Kuiper belt and scattered disk, exhibit low-inclination chaotic trajectories due to close encounters with Jupiter. Despite their typically short incursions into inner solar system, a notable number of them are on Earth-crossing orbits, fireball networks detecting many objects “JFC-like” (2 < T J 3) orbits. Aims This investigation aims examine orbital dynamics JFCs comet-like fireballs over 10 4 yr timescales, focusing...

Potentially Hazardous Asteroids and meteorites are delivered to near-Earth space via the same mechanisms, for modelling purposes it is often assumed that they similarly distributed across orbital space. Thanks 9 years of large meteoroid impact monitoring by Desert Fireball Network, we have direct evidence two populations dynamically different. We find a key transition happens in unobserved gap between meteoroids regularly drop (0.1-1 m) sizes covered Near-Earth Objects models (>35 m)....
Jupiter-family comets (JFCs) originate from the Kuiper belt and scattered disk, characterized by short orbital periods frequent interactions with Jupiter. Their icy composition a chaotic transition to inner solar system result in dynamic physical lifetimes. These features make JFCs key subjects for understanding migration of celestial bodies possibly delivery organic materials early Earth. Numerous studies fireballs have historically posited substantial contribution large objects JFC orbits,...
BackgroundJupiter-family comets (JFCs) are distinct low-inclination predominantly originating from the Kuiper belt and scattered disk. These regions, extending beyond Neptune&#8217;s orbit, home to icy primitive bodies that have retained many of their volatile components. JFCs, characterized by short orbital periods (

NEO models for km-sized asteroids&#160;&#160; Near-Earth object (NEO) are a useful tool interpreting asteroid behaviour in near-Earth space (perihelion distances < 1.3 au). They can predict many properties such the size-dependent transport from main-belt (Granvik et al., 2018; Nesvorn&#253; 2023) and disruptive processes of low perihelia passage 2016; Wiegart 2020). also estimate frequency Earth impactors (Harris &amp; Chodas, 2021; Morbidelli 2020), trace origins...
