VLTI/MATISSE observations of the hot dust around Pictoris: Observing faint objects with MATISSE
P. Priolet, J. -C. Augereau, J. Milli +32
Context: Hot exozodiacal dust has been detected around approximately 20% of nearby main-sequence stars, indicating that it is a common feature of extrasolar planetary systems. Howe…
CHEOPS's hunt for exocomets: photometric observations of 5 Vul
Isabel Rebollido, Sebastian Zieba, Daniela Iglesias +3
The presence of minor bodies in exoplanetary systems is in most cases inferred through infra-red excesses, with the exception of exocomets. Even if over 35 years have passed since…
Morphology of the gas-rich debris disk around HD 121617 with SPHERE observations in polarized light
Clément Perrot, Johan Olofsson, Quentin Kral +7
Debris disks are the signposts of collisionally eroding planetesimal circumstellar belts, whose study can put important constraints on the structure of extrasolar planetary systems…
X-Shooter Survey of Young Intermediate Mass Stars -- I. Stellar Characterization and Disc Evolution
Daniela P. Iglesias, Olja Panić, Mario van den Ancker +6
Intermediate mass stars (IMSs) represent the link between low-mass and high-mass stars and cover a key mass range for giant planet formation. In this paper, we present a spectrosco…
A HARPS radial velocity search for planets in the Scorpius-Centaurus association. And its combination with the HARPS and SOPHIE young nearby stars (YNS) surveys
Antoine Grandjean, A. -M. Lagrange, N. Meunier +13
The Scorpius-Centaurus (Sco-Cen) young and nearby massive star-forming region is particularly well suited for extrasolar planet searches with both direct imaging and radial velocit…
Identification and spectroscopic characterization of 128 new Herbig stars
Miguel Vioque, René D. Oudmaijer, Chumpon Wichittanakom +6
We present optical spectroscopy observations of 145 high-mass pre-main sequence candidates from the catalogue of Vioque et al. (2020). From these, we provide evidence for the Herbi…
Exocomets from a Solar System Perspective
Paul A. Strøm, Dennis Bodewits, Matthew M. Knight +24
Exocomets are small bodies releasing gas and dust which orbit stars other than the Sun. Their existence was first inferred from the detection of variable absorption features in ste…
Exocomets: A spectroscopic survey
I. Rebollido, C. Eiroa, B. Montesinos +18
While exoplanets are now routinely detected, the detection of small bodies in extrasolar systems remains challenging. Since the discovery of sporadic events interpreted as exocomet…
An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
Dust production in the debris disk around HR 4796 A
J. Olofsson, J. Milli, P. Thébault +21
Debris disks are the natural by-products of the planet formation process. Scattered or polarized light observations are mostly sensitive to small dust grains that are released from…
Debris disks with multiple absorption features in metallic lines: circumstellar or interstellar origin?
D. Iglesias, A. Bayo, J. Olofsson +8
Debris disks are second generation dusty disks thought to be devoid of gas. However, this idea has been challenged in the last years by gas detections in some systems. We compiled…
Sub-millimeter non-contaminated detection of the disk around TWA\,7 by ALMA
A. Bayo, J. Olofsson, L. Matra +9
Debris disks can be seen as the left-overs of giant planet formation and the possible nurseries of rocky planets. While M-type stars out-number more massive stars we know very litt…
The co-existence of hot and cold gas in debris discs
I. Rebollido, C. Eiroa, B. Montesinos +19
Debris discs have often been described as gas-poor discs as the gas-to-dust ratio is expected to be considerably lower than in primordial,protoplanetary discs. However, recent obse…
Exocomet signatures around the A-shell star Leo?
C. Eiroa, I. Rebollido, B. Montesinos +18
We present an intensive monitoring of high-resolution spectra of the Ca {\sc ii} K line in the A7IV shell star Leo at very short (minutes, hours), short (night to night), and m…
M dwarfs in the b201 tile of the VVV survey: Colour-based Selection, Spectral Types and Light Curves
Bárbara Rojas-Ayala, Daniela Iglesias, Dante Minniti +2
The intrinsically faint M dwarfs are the most numerous stars in the Galaxy, have main-sequence lifetimes longer than the Hubble time, and host some of the most interesting planetar…
