Pre-nova Observations of T CrB: A view from the CHARA Array
Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38
T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…
Unveiling Dominant Toroidal Magnetic Fields in a Protostellar Outflow
Tao-Chung Ching, Zhi-Yun Li, Qizhou Zhang +6
Magnetic fields play a fundamental role in the formation of protostellar winds. In the magneto-centrifugal models, poloidal magnetic fields launch winds from accretion disks, and f…
Magnetic field measurements in a sample of Class I and flat-spectrum protostars observed with SPIRou
L. Drouglazet, E. Alecian, A. Sousa +27
Magnetic fields play a crucial role throughout stellar evolution, regulating angular momentum, channelling accretion, and launching jets and outflows. While the magnetic properties…
PRODIGE -- envelope to disk with NOEMA VIII. Sulfur oxides trace a shock caused by a streamer in the inner envelope of a protostar
María Teresa Valdivia-Mena, Jaime E. Pineda, Caroline Gieser +24
(Abridged) Recently, streamers have been observed causing shocks at the outer edge of protoplanetary disks. The study of sulfur-bearing species can help us to understand the physic…
Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses
Luigi Zallio, Miguel Vioque, Sean M. Andrews +14
Stellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung-Russell (HR) diagrams are strongly model de…
The accretion-ejection connection in the asymmetric Th 28 jet revealed by MUSE-NFM
A. Murphy, E. T. Whelan, F. Bacciotti +5
Mass loss through stellar jets is closely tied to the process of accretion through the disk. Understanding phenomena such as episodic ejections and outflow asymmetries can thus she…
HOPS-288: A Laboratory for Complex Organics in Proto-multiple Systems
Shih-Ying Hsu, Nadia M. Murillo, Chin-Fei Lee +21
Complex organic molecules (COMs) in young stellar objects (YSOs) have attracted significant attention in recent years due to their potential connection to pre-biotic chemistry and…
The 12CO Gas Structures of Protoplanetary Disks in the Upper Scorpius Region
Luigi Zallio, Giovanni P. Rosotti, Miguel Vioque +13
We present measurements of key protoplanetary disk properties inferred from parametric models of ALMA 12CO spectral line visibilities. We derive gas-disk radii, integrated fluxes,…
The nature of ASASSN-24fw's occultation: modelling the event as dimming by optically thick rings around a sub-stellar companion
Sarang Shah, Jonathan P. Marshall, Carlos del Burgo +12
ASASSN-24fw is a main-sequence F-type star that experienced a rapid and long-lasting dimming event beginning in late 2024 and continuing until mid 2025. Its pre-dimming spectral en…
Variability of the DG Tau Forbidden Emission Line Low Velocity Component
Noah Otten, Emma Whelan, Yu-Ru Chou +3
Optical Forbidden Emission Lines (FELs) come from transitions with long radiative decay times needing low density gas where collisions between atoms are rare. They are produced in…
Critical Metallicity of Cool Supergiant Formation. II. Physical Origin
Po-Sheng Ou, Ke-Jung Chen
This study investigates the physical origin of the critical metallicity required for the formation of cool supergiants, as revealed by stellar evolution models. Using grids of stel…
Erosion of a dense molecular core by a strong outflow from a massive protostar
J. A. López-Vázquez, M. Fernández-López, J. M. Girart +6
We present Atacama Large Millimeter/submillimeter Array Band 3 observations of NH (1-0) and CHCN (5-4), as well as Band 7 observations of the HCO molecular line emi…
Evidence of a Disk-wind Origin for Fluorescent H in Classical T Tauri Stars
Matt Kalscheur, Kevin France, Brunella Nisini +8
We use FUV spectra of 36 T Tauri stars, predominately from 's ULLYSES program, to examine the kinematic properties of fluorescent H emission li…
Investigating the asymmetry of young stellar outflows: Combined MUSE-X-shooter study of the Th 28 jet
A. Murphy, E. T. Whelan, F. Bacciotti +7
Characterising stellar jet asymmetries is key to setting robust constraints on jet launching models and improving our understanding of the underlying mechanisms behind jet launchin…
