The Morphology and Kinematics of a Giant, Symmetric Nebula around a Radio-loud Quasar 3C 57: Extended Rotating Gas or Biconical Outflows?

The Astrophysical Journal
Gas flows between galaxies and the circumgalactic medium play a crucial role in galaxy evolution. When ionized by a quasar, these gas flows can be directly traced as giant nebulae. We present a study of a giant nebula around a radio-loud quasar, 3C 57 at

Planetary Nebulae Research: Past, Present, and Future [PDF]

Galaxies 2024, 12, 39
We review the evolution of our understanding of the planetary nebulae phenomenon and their place in the scheme of stellar evolution. The historical steps leading to our current understanding of central star evolution and nebular formation are discussed.

Chondrule Survivability in the Solar Nebula

The Astrophysical Journal
The lifetime of millimeter-sized dust grains, such as chondrules, in the nominal solar nebula model is limited to ∼10 ^5 yr, due to an inward drift driven by gas drag.

LBV (Candidate) Nebulae: Bipolarity and Outflows [PDF]

arXiv, 2002
The most massive evolved stars (above 50 M_sun) undergo a phase of extreme mass loss in which their evolution is reversed from a redward to a blueward motion in the HRD. In this phase the stars are known as Luminous Blue Variables (LBVs) and they are located in the HRD close to the Humphreys-Davidson limit.

Ring Nebulae around Massive Stars throughout the HR Diagram [PDF]

arXiv, 2002
Massive stars evolve across the HR diagram, losing mass along the way and forming a variety of ring nebulae. During the main sequence stage, the fast stellar wind sweeps up the ambient interstellar medium to form an interstellar bubble. After a massive star evolves into a red giant or a luminous blue variable, it loses mass copiously to form a ...
