Exploring the formation pathways of formamide near young O-type stars
Veronica Allen, Floris F. S. van der Tak, Ana López-Sepulcre +4
Context. As a building block for amino acids, formamide (NHCHO) is an important molecule in astrobiology and astrochemistry, but its formation path in the interstellar medium i…
High-Resolution Near-Infrared Polarimetry and Sub-Millimeter Imaging of FS Tau A: Possible Streamers in Misaligned Circumbinary Disk System
Yi Yang, Eiji Akiyama, Thayne Currie +56
We analyzed the young (2.8-Myr-old) binary system FS Tau A using near-infrared (H-band) high-contrast polarimetry data from Subaru/HiCIAO and sub-millimeter CO (J=2-1) line emissio…
SUBARU Near-Infrared Imaging Polarimetry of Misaligned Disks Around The SR24 Hierarchical Triple System
Satoshi Mayama, Sebastián Pérez, Nobuhiko Kusakabe +65
The SR24 multi-star system hosts both circumprimary and circumsecondary disks, which are strongly misaligned from each other. The circumsecondary disk is circumbinary in nature. In…
Spectral library of age-benchmark low-mass stars and brown dwarfs
E. Manjavacas, N. Lodieu, V. J. S. Béjar +3
In the past years, some extremely red brown dwarfs were found. They were believed to have low surface gravity, but many of their spectral characteristics were similar to those of h…
The magnetic field and accretion regime of CI Tau
JF Donati, J Bouvier, SH Alencar +7
This paper exploits spectropolarimetric data of the classical T Tauri star CI Tau collected with ESPaDOnS at the Canada-France-Hawaii Telescope, with the aims of detecting and char…
Imaging the 44 AU Kuiper Belt-analogue debris ring around HD 141569A with GPI polarimetry
J. S. Bruzzone, S. Metchev, G. Duchene +53
We present the first polarimetric detection of the inner disk component around the pre-main sequence B9.5 star HD 141569A. Gemini Planet Imager H-band (1.65 micron) polarimetric di…
No evidence of a sudden change of spectral appearance or magnetic field strength of the O9.7V star HD 54879
G. A. Wade, S. Bagnulo, Z. Keszthelyi +8
It was recently claimed that the magnetic O-type star HD 54879 exhibits important radial velocity variability indicative of its presence in a spectroscopic binary. More remarkably,…
Time-resolved photometry of the young dipper RX J1604.3-2130A: Unveiling the structure and mass transport through the innermost disk
A. Sicilia-Aguilar, C. F. Manara, J. de Boer +3
RX~J1604.3-2130A is a young, dipper-type, variable star in the Upper Scorpius association, suspected to have an inclined inner disk with respect to its face-on outer disk. We study…
Activity time series of old stars from late F to early K. IV. Limits of the correction of radial velocities using chromospheric emission
Nadège Meunier, Anne-Marie Lagrange, Sylvain Cuzacq
Inhibition of the convective blueshift in active regions is a major contribution to the radial velocity variations, at least for solar-like stars. A common technique to correct for…
The GRAVITY Young Stellar Object survey -- I. Probing the disks of Herbig Ae/Be stars in terrestrial orbits
K. Perraut, L. Labadie, B. Lazareff +69
The formation and the evolution of protoplanetary disks are important stages in the lifetime of stars. The processes of disk evolution and planet formation are intrinsically linked…
Detection of a low-mass stellar companion to the accelerating A2IV star HR 1645
Robert J. De Rosa, Eric L. Nielsen, Julien Rameau +50
The \, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {…
Investigating the nature of the extended structure around the Herbig star RCrA using integral field and high-resolution spectroscopy
E. Rigliaco, R. Gratton, D. Mesa +24
We present a detailed analysis of the extended structure detected around the young and close-by Herbig Ae/Be star RCrA. This is a young triple system with an intermediate mass cent…
Rotational evolution of solar-type protostars during the star-disk interaction phase
Florian Gallet, Claudio Zanni, Louis Amard
The early pre-main sequence phase during which they are still likely surrounded by an accretion disk represents a puzzling stage of the rotational evolution of solar-mass stars. Wh…
The HH 212 interstellar laboratory: astrochemistry as a tool to reveal protostellar disks on Solar System scales around a rising Sun
Claudio Codella, Cecilia Ceccarelli, Chin-Fei Lee +8
The investigation of star forming regions have enormously benefited from the recent advent of the ALMA interferometer. More specifically, the unprecedented combination of high-sens…
Testing the Spectroscopic Extraction of Suppression of Convective Blueshift
M. Miklos, T. W. Milbourne, R. D. Haywood +21
Efforts to detect low-mass exoplanets using stellar radial velocities (RVs) are currently limited by magnetic photospheric activity. Suppression of convective blueshift is the domi…
Reactivity of HCO with CH3 and NH2 on Water Ice Surfaces. A Comprehensive Accurate Quantum Chemistry Study
Joan Enrique-Romero, Albert Rimola, Cecilia Ceccarelli +3
Interstellar complex organic molecules (iCOMs) can be loosely defined as chemical compounds with at least six atoms in which at least one is carbon. The observations of iCOMs in st…

Ana López-Sepulcre, Nadia Balucani, Cecilia Ceccarelli +3
Formamide (NHCHO) has been identified as a potential precursor of a wide variety of organic compounds essential to life, and many biochemical studies propose it likely played a…
Does magnetic field impact tidal dynamics inside the convective zone of low-mass stars along their evolution?
A. Astoul, S. Mathis, C. Baruteau +5
The dissipation of the kinetic energy of wave-like tidal flows within the convective envelope of low-mass stars is one of the key physical mechanisms that shapes the orbital and ro…
