JWST/MIRI Detection of Molecular H Winds from an Edge-on Class II Source HV Tau C

Vinod Chandra Pathak, P. Manoj, Himanshu Tyagi +14

The evolution of protoplanetary disks is regulated by accretion onto the central star and mass loss through jets and winds. While atomic and ionized outflows are commonly observed,…

MINDS: Intertwined evolution of dust and gas in large planet-forming disks. A diversity driven by halted pebble drift?

Benoît Tabone, Milou Temmink, Laurens B. F. M. Waters +25

(Abridged) We aim to investigate the inner regions of large and massive disks orbiting T Tauri stars, thought to be progenitors of systems with wide-orbit planets and possible case…

Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

MINDS: Detection of an inner gas disk caused by evaporating bodies around HD 172555

M. Samland, T. Henning, A. Caratti o Garatti +23

Mechanisms such as collisions of rocky bodies or cometary activity give rise to dusty debris disks. Debris disks trace the leftover building blocks of planets, and thus also planet…

MINDS. Water reservoirs of compact planet-forming dust disk: A diversity of HO distributions

Milou Temmink, Andrew D. Sellek, Danny Gasman +17

Millimetre-compact dust disks are thought to have efficient radial drift of icy dust pebbles, which has been hypothesised to produce an enhanced cold (400 K) HO reservoir i…

MINDS. Anatomy of a water-rich, inclined, brown dwarf disk: lack of abundant hydrocarbons

Giulia Perotti, Nicolás T. Kurtovic, Thomas Henning +23

2MASS J04381486+2611399 (or J0438) is one of the few young brown dwarfs (BD) with a highly inclined () disk. Here we report results from JWST-MIRI MRS, HST-ACS a…

HCN and C2H2 in the atmosphere of a T8.5+T9 brown dwarf binary

Elisabeth C. Matthews, Paul Mollière, Helena Kühnle +22

T-type brown dwarfs present an opportunity to explore atmospheres teeming with molecules such as H2O, CH4 and NH3, which exhibit a wealth of absorption features in the mid-infrared…

First unambiguous detection of ammonia in the atmosphere of a planetary mass companion with JWST/MIRI coronagraphs

Mathilde Mâlin, Anthony Boccaletti, Clément Perrot +28

The newly accessible mid-infrared (MIR) window offered by the James Webb Space Telescope (JWST) for exoplanet imaging is expected to provide valuable information to characterize th…

MINDS. JWST-MIRI reveals a peculiar CO-rich chemistry in the drift-dominated disk CX Tau

Marissa Vlasblom, Milou Temmink, Sierra L. Grant +20

Radial drift of icy pebbles can have a large impact on the chemistry of the inner regions of protoplanetary disks. Compact dust disks (50 au) are suggested to have a high…

Combined analysis of the 12.8 and 15 JWST/MIRI eclipse observations of TRAPPIST-1 b

Elsa Ducrot, Pierre-Olivier Lagage, Michiel Min +36

The first JWST/MIRI photometric observations of TRAPPIST-1 b allowed for the detection of the thermal emission of the planet at 15 , suggesting that the planet could be a bare…

Unveiling the HD 95086 system at mid-infrared wavelengths with JWST/MIRI

Mathilde Mâlin, Anthony Boccaletti, Clément Perrot +26

Mid-infrared imaging of exoplanets and disks is now possible with the coronagraphs of the MIRI on the JWST. This wavelength range unveils new features of young directly imaged syst…

TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf

Faith Hawthorn, Daniel Bayliss, Thomas G. Wilson +137

We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ( mag), high proper motion…

The AU Mic Debris Disk: far-infrared and submillimeter resolved imaging

Brenda C. Matthews, Grant Kennedy, Bruce Sibthorpe +20

We present far-infrared and submillimeter maps from the Herschel Space Observatory and the James Clerk Maxwell Telescope of the debris disk host star AU Microscopii. Disk emission…

Centauri A in the far infrared

R. Liseau, B. Montesinos, G. Olofsson +15

Chromospheres and coronae are common phenomena on solar-type stars. Understanding the energy transfer to these heated atmospheric layers requires direct access to the relevant empi…

The mid-infrared extinction in molecular clouds Case study of B 335

Sven Olofsson, Göran Olofsson

The purpose of the investigation is to probe the dust properties inside a molecular cloud, how particle grow and how the presence of ice coatings may change the overall shape of th…

The extinction law for molecular clouds. Case study of B 335

Sven Olofsson, Göran Olofsson

We determine the extinction curve from the UV to the near-IR for molecular clouds and investigate whether current models can adequately explain this wavelength dependence of the ex…

A new method of determining distances to dark globules. The distance to B 335

Sven Olofsson, Göran Olofsson

We observed a test globule, B 335 in U, B, g, r, and I, and together with the 2MASS survey, this data set gives a well-defined spectral energy distribution (SED) of a large number…
