The Preliminary Mauve Science Programme: Science themes identified for the first year of operations
Mauve Science Collaboration, Marcel Agueros, Don Dixon +22
Mauve is a low-cost small satellite developed and operated by Blue Skies Space Ltd. The payload features a 13 cm telescope connected with a fibre that feeds into a UV-Vis spectrome…
Coordinated Space- and Ground-based Monitoring of Accretion Bursts in a Protoplanetary Disk: The Orbital and Accretion Properties of DQ Tau
Hala Alqubelat, Carlo F. Manara, Justyn Campbell-White +9
Multiplicity in pre-main-sequence (PMS) systems shapes circumstellar and circumbinary disks, often producing features such as inner cavities, spiral arms, and gas streamers that fa…
Variability of the DG Tau Forbidden Emission Line Low Velocity Component
Noah Otten, Emma Whelan, Yu-Ru Chou +3
Optical Forbidden Emission Lines (FELs) come from transitions with long radiative decay times needing low density gas where collisions between atoms are rare. They are produced in…
Coordinated Space and Ground-Based Monitoring of Accretion Bursts in a Protoplanetary Disk: Establishing Mid-Infrared Hydrogen Lines as Accretion Diagnostics for JWST-MIRI
Benjamin M. Tofflemire, Carlo F. Manara, Andrea Banzatti +17
In this paper, we establish and calibrate mid-infrared hydrogen recombination lines observed with JWST as accretion tracers for pre-main-sequence stars that accrete from circumstel…
A Spectroastrometric Study of the Low-velocity Wind from DG Tau A
Yu-Ru Chou, Michihiro Takami, Shin-Ping Lai +9
We obtained high spectral resolution spectra ( 2.5 km s) for DG Tau A from 4800 Å to 7500 Å using Subaru High Dispersion Spectrograph (HDS) for the first time. Th…
Forbidden Emission Line spectro-imaging of the RU Lupi jet and Low Velocity Component
M. Birney, E. T. Whelan, C. Dougados +5
The first images of the jet and low velocity component (LVC) from the strongly accreting classical T Tauri star RU Lupi are presented. Adaptive optics assisted spectro-imaging of f…
Jets from the Upper Scorpius Variable Young Star System 2MASS J16075796-2040087 Via KECK/HIRES Spectro-astrometry
Emma Whelan, Miriam Keppler, Neal Turner +4
2MASS J16075796-2040087 is a ~ 5 Myr young star in Upper Sco with evidence for accretion bursts on a timescale of about 15 days and, uncommonly for its age, outflows traced by mult…
A kinematical study of the launching region of the blueshifted HH 46/47 outflow with SINFONI K-band observations
M. Birney, C. Dougados, E. T. Whelan +3
Studying outflows is important as they may significantly contribute to angular momentum removal from the star/disk system, affecting disk evolution and planet formation. To investi…
Full L- and M-band high resolution spectroscopy of the S CrA binary disks with VLT-CRIRES+
Sierra L. Grant, Giulio Bettoni, Andrea Banzatti +7
The Cryogenic IR echelle Spectrometer (CRIRES) instrument at the Very Large Telescope (VLT) was in operation from 2006 to 2014. Great strides in characterizing the inner regions of…
Optical Forbidden Emission Line Spectro-astrometry of T CrA: Evidence for a Multiple System and Multiple Jets
Emma Whelan, Aisling Murphy, Ilaria Pascucci
Spectro-astrometry is applied to echelle spectra of the young intermediate mass star T CrA. The aim is to better understand the origin of the [O I] and [S II] emission from T CrA a…
Discovery of a jet from the single HAe/Be star HD 100546
P. C. Schneider, C. Dougados, E. T. Whelan +6
Young accreting stars drive outflows that collimate into jets, which can be seen hundreds of au from their driving sources. Accretion and outflow activity cease with system age, an…
First large scale Herbig-Haro jet driven by a proto-brown dwarf
B. Riaz, C. Briceno, E. Whelan +1
We report the discovery of a new Herbig-Haro jet, HH 1165, in SOAR narrow-band imaging of the vicinity of the sigma Orionis cluster. HH 1165 shows a spectacular extended and collim…
Optical spectroscopy of the Be/X-ray Binary V850 Cen/GX 304-1 during faint X-ray periodical activity
C. Malacaria, W. Kollatschny, E. Whelan +4
Be/X-ray binaries are the most populous class of High Mass X-ray Binaries. Their X-ray duty cycle is tightly related to the optical companion wind activity, which in turn can be st…
HH 1158: The lowest luminosity externally irradiated Herbig-Haro jet
B. Riaz, E. T. Whelan
We have identified a new externally irradiated Herbig-Haro (HH) jet, HH 1158, within ~2 pc of the massive OB type stars in the sigma Orionis cluster. At an Lbol ~ 0.1 Lsun, HH 1158…
Spectro-astrometry of LkCa 15 with X-Shooter: Searching for emission from LkCa 15b
E. T. Whelan, N. Huelamo, J. M. Alcala +5
Planet formation is one explanation for the partial clearing of dust observed in the disks of some T Tauri stars. Indeed studies using state-of-the-art high angular resolution tech…
