EX Lup is the prototype of the EXor class of eruptive young stars. These objects show optical outbursts which are thought to be related to runaway accretion onto the star. In a previous study we observed in situ crystal formation in the disk of EX Lup during its latest outburst in 2008, making the object an ideal laboratory to investigate circumstellar crystal formation and transport. This outburst was monitored by a campaign of ground-based and Spitzer Space Telescope observations. Here we… Expand
Spectral Evolution and Radial Dust Transport in the Prototype Young Eruptive System EX Lup
EX Lup is the prototype of a class of pre-main sequence eruptive stars defined by their repetitive outbursts lasting several months. In 2008 January-September EX Lup underwent its historicallyExpand
Outbursts of young Sun-like stars may change how terrestrial planets form
Abstract While the Sun is nowadays a quiet and well-balanced star, in its first few million years it might have been often out of temper, like those young low-mass stars which episodically undergoExpand
Chemical Signatures of the FU Ori Outbursts
The FU Ori-type young stellar objects are characterized by a sudden increase in luminosity by 1$-$2 orders of magnitude, followed by slow return to the pre-outburst state on timescales ofExpand
Radial velocity variations in the young eruptive star EX Lupi
Context. EX Lup-type objects (EXors) are low-mass pre-main sequence objects characterized by optical and near-infrared outbursts attributed to highly enhanced accretion from the circumstellar diskExpand
Dynamics during outburst: VLTI observations of the young eruptive star V1647 Orionis during its 2003-2006 outburst
Context. It is hypothesized that low-mass young stellar objects undergo eruptive phases during their early evolution. These eruptions are thought to be caused by highly increased mass accretion fromExpand
The Circumstellar Disk and Asymmetric Outflow of the EX Lup Outburst System
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations at 0.3 arcsec-resolution of EX Lup, the prototype of the EXor class of outbursting pre-main sequence stars. TheExpand
EX Lupi FROM QUIESCENCE TO OUTBURST : EXPLORING THE LTE APPROACH IN MODELING BLENDED H2O AND OH MID-INFRARED EMISSION
We present a comparison of archival Spitzer spectra of the strongly variable T Tauri EX Lupi, observed before and during its 2008 outburst. We analyze the mid-infrared emission from gas-phaseExpand
The role of protostellar jets in star formation and the evolution of the early solar system: Astrophysical and meteoritical perspectives
– The rock record from the early solar system indicates high-temperature thermal processing sufficient to melt refractory oxides and silicates. The astrophysical context for the formation andExpand
Depletion of molecular gas by an accretion outburst in a protoplanetary disk
We investigate new and archival 3-5 $\mu$m high resolution ($\sim3$ km s$^{-1}$) spectroscopy of molecular gas in the inner disk of the young solar-mass star EX Lupi, taken during and after theExpand
Exploring the circumstellar environment of the young eruptive star V2492 Cygni
Context. V2492 Cyg is a young eruptive star that went into outburst in 2010. The near-infrared color changes observed since the outburst peak suggest that the source belongs to a newly definedExpand

The 2008 Extreme Outburst of the Young Eruptive Variable Star EX Lupi
In early 2008, the young low-mass star EX Lupi, the prototype of the EXor class of eruptive variables, optically brightened by over 5 mag for a period of seven months. The previous time a change ofExpand
Near-infrared spectroscopy of EX Lupi in outburst
EX Lup is the prototype of the EXor class of young eruptive stars: objects showing repetitive brightenings due to increased accretion from the circumstellar disk to the star. In this paper, we reportExpand
EX Lupi in quiescence
Aims. EX Lupi is the prototype of EXors, a subclass of low-mass pre-main sequence stars whose episodic eruptions are attributed to temporarily increased accretion. In quiescence the optical andExpand
Episodic formation of cometary material in the outburst of a young Sun-like star
TLDR
Mid-infrared features in the outburst spectrum of the young Sun-like star EX Lupi that were not present in quiescence are reported and it is concluded that the crystals were produced through thermal annealing in the surface layer of the inner disk by heat from the outburst, a process that has hitherto not been considered.

Fundamental vibrational transition of CO during the outburst of EX Lupi in 2008
We report monitoring observations of the T Tauri star EX Lupi during its outburst in 2008 in the CO fundamental band at 4.6–5.0 μm. The observations were carried out at the Very Large Telescope andExpand
The Structure and Emission of the Accretion Shock in T Tauri Stars
We have examined one of the key predictions of the magnetospheric infall model for classical T Tauri stars (CTTS), namely, the formation of a shock on the stellar surface. We find that accretionExpand
Evolution of Dust and Ice Features around FU Orionis Objects
We present spectra for a sample of 14 FUors and two T Tauri stars observed with Spitzer or ISO. Based on the appearance of the 10 μm silicate feature, we define two categories of FUors. ObjectsExpand
