Spectral Ratio Analysis: probing of a new suite of stellar activity indicators as a tool for astrophysical noise mitigation
Jean C. Costes, Christopher A. Watson, Ernst de Mooij +6
Stellar activity is the main barrier to detecting and/or confirming low-mass/long-period (and Earth-analogue) planets using radial-velocity (RV) measurements. Searching for reliabl…

Observations of highly inclined disks with ALMA. Results from 12CO gas and continuum observations
Laurine Martinien, Gaspard Duchêne, Álvaro Ribas +4
[Abridged] We aim to study the radial and vertical extents of 12CO gas, millimeter dust thermal emission and optical/NIR scattered light by dust in disks. We analyze a sample of 14…
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…
Dust traps and gas kinematic signatures in a crescent structure of a planet-forming disk
Greta Guidi, François Menard, Daniel J. Price +2
In the past few years, ALMA unveiled a variety of substructures (rings, spirals, crescents) in the continuum emission of most protoplanetary disks imaged at high spatial resolution…
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…
FAUST XXX: Dust enhancement in the young binary L1551 IRS 5
Nicolás Cuello, Eleonora Bianchi, François Ménard +17
Young binary stars with discs provide unique laboratories to study the earliest stages of planet formation in star-forming environments. The detection of substructure in discs arou…
Weakened inspirals -- I: High mass ratio common envelope interactions in RGB stars
Jack Patrick Nibbs, Orsola De Marco, Lionel Siess +2
The common envelope (CE) interaction between an expanding giant star and a compact companion typically leads to a rapid orbital decay, ending in either a merger or the formation of…
Substellar Initial Mass Function of Trumpler 14
Tamara Rom, Estelle Moraux, Koraljka Mužić +3
Young, massive stellar clusters offer a prime setting to explore brown dwarf (BD) formation under high densities and intense UV radiation. Trumpler 14 (Tr 14), a 1 Myr-old cluster…
Variation of the disk thickness across ice bands: A method to determine ice abundances in highly inclined protoplanetary disks
Laurine Martinien, Gaspard Duchêne, François Ménard +6
The James Webb Space Telescope provides unprecedented information to study ices in protoplanetary disks. However, the saturation of ice bands in highly inclined disks hinders the m…
Resolution and calibration effects in high contrast polarimetric imaging of circumstellar scattering regions
H. M. Schmid, J. Ma
Many circumstellar dust scattering regions have been detected and investigated with polarimetric imaging. However, the quantitative determination of the intrinsic polarization and…
