Evolved Massive Stars at Low Metallicity. VII. The Lower Mass Limit of the Red Supergiant Population in the Large Magellanic Cloud by Ming Yang, Bo Zhang, Biwei Jiang, Jian Gao, Yi Ren, Shu Wang, Man I Lam, Hao Tian, Changqing Luo, Bingqiu Chen, Jing Wen

“…Here, we assemble a spectroscopic evolved cool star sample with 6602 targets, including RSGs, asymptotic giant branch stars, and red giant branch stars, in the Large Magellanic Cloud based on Gaia DR3 and Sloan Digital Sky Survey IV/APOGEE-2. …”

Revised Architecture and Two New Super-Earths in the HD 134606 Planetary System by Zhexing Li, Stephen R. Kane, Timothy D. Brandt, Tara Fetherolf, Paul Robertson, Jinglin Zhao, Paul A. Dalba, Robert A. Wittenmyer, R. Paul Butler, Matías R. Díaz, Steve B. Howell, Jeremy Bailey, Brad Carter, Elise Furlan, Crystal L. Gnilka, Jonathan Horner, Hugh R. A. Jones, Simon O’Toole, Chris Tinney

“…HD 134606 now displays four low-mass planets in a compact region near the star, one gas giant further out in the habitable zone, an additional companion in the outer regime, and a low-mass M dwarf stellar companion at large separation, making it an intriguing target for system formation/evolution studies. …”

The Gemini NICI Planet-Finding Campaign: The Frequency of Giant Planets around Young B and A Stars by Nielsen, E, Liu, M, Wahhaj, Z, Biller, B, Hayward, T, Close, L, Males, JR, Skemer, A, Chun, M, Ftaclas, C, Alencar, S, Artymowicz, P, Boss, A, Clarke, F, Pino, E, Gregorio-Hetem, J, Hartung, M, Ida, S, Kuchner, M, Lin, D, Reid, I, Shkolnik, E, Tecza, M, Thatte, N, Toomey, D

“…Considering the contrast limits of our NICI data and the fact that we did not detect any planets, we use high-fidelity Monte Carlo simulations to show that fewer than 20% of 2 M_sun stars can have giant planets greater than 4 M_Jup between 59 and 460 AU at 95% confidence, and fewer than 10% of these stars can have a planet more massive than 10 M_Jup between 38 and 650 AU. …”

Common envelope ejection in massive binary stars - Implications for the progenitors of GW150914 and GW151226 by Kruckow, M, Tauris, T, Langer, N, Szecsi, D, Marchant, P, Podsiadlowski, P

“…</p> <h4>Results</h4> <p>In addition to producing double white dwarf and double neutron star binaries, CE evolution may also produce massive BH-BH systems with individual BH component masses of up to ~50 60 M⊙, in particular for donor stars evolved to giants beyond the Hertzsprung gap. However, the physics of envelope ejection of massive stars remains uncertain. …”

The Structure of the Molecular Envelope of the Ring Nebula (NGC 6720) by Joel H. Kastner, David J. Wilner, Diana Ryder, Paula Moraga Baez, Orsola De Marco, Raghvendra Sahai, Alwyn Wootten, Albert Zijlstra

“…We assert that the Ring’s molecular envelope represents the “fossil” remnant of a relatively sudden mass ejection ∼6000 yr ago that terminated the progenitor star’s asymptotic giant branch (AGB) evolution, and that this ellipsoidal envelope of AGB ejecta was then punctured by fast, collimated polar outflows or jets resulting from interactions between the progenitor and one or more companion stars. …”
