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…
