Unveiling Ionized Jet Morphologies: Sub-arcsecond VLA Observations of Compact Radio Sources

Tatiana M. Rodriguez, Peter Hofner, Emmanuel Momjian +3

We present sub-arcsecond () resolution VLA 1.3 cm continuum and 22.2 GHz HO maser observations toward 15 compact radio continuum sources with rising sp…

High Resolution Overtone Spectroscopy of HNC and HCN

Miguel Jiménez-Redondo, Chiara Schleif, Julianna Palotás +5

Rotationally resolved spectra of the HNC and HCN molecular ions have been recorded in the spectral range between 6200 and 6800 \rcm\ using a cryogenic ion trap instrument.…

Precise determination of circumstellar disk lifetimes: Disk evolution in a single star-forming region

Fabian A. Polnitzky, Sebastian Ratzenböck, Josefa E. Großschedl +1

Determining how long circumstellar disks last is key to understanding the timescale of planet formation. Typically, this is done by measuring the fraction of young stars with infra…

Dark-Matter-Powered Population III Evolution: Lifetimes, Rotation, and Quasi-Homogeneity in massive Stars

Anais Pauchet, Devesh Nandal

Population III stars supplied the first light and metals in the Universe, setting the pace of re-ionisation and early chemical enrichment. In dense haloes their evolution can be st…

Exploring stellar activity in a sample of active M dwarfs

A. S. Rajpurohit, V. Kumar, K. Srivastava Mudit +3

Most M dwarfs show higher chromospheric activity, often exceeding solar levels. Characterizing stellar activity is essential, particularly since these stars are prime targets in th…

ATOMIUM: Continuum emission and evidence of dust enhancement from binary motion

T. Danilovich, N. Samaratunge, Y. Mori +35

Low- and intermediate-mass stars on the asymptotic giant branch (AGB) account for a significant portion of the dust and chemical enrichment in their host galaxy. Here we present AL…
