Cold CO gas in the envelopes of FU Orionis-type young eruptive stars
Á. Kóspál, P. Ábrahám, T. Csengeri +3
FUors are young stellar objects experiencing large optical outbursts due to highly enhanced accretion from the circumstellar disk onto the star. FUors are often surrounded by massi…
Discovery of molecular gas around HD 131835 in an APEX molecular line survey of bright debris disks
A. Moór, Th. Henning, A. Juhász +11
Debris disks are considered to be gas-poor, but recent observations revealed molecular or atomic gas in several 10-40 Myr old systems. We used the APEX and IRAM 30m radiotelescopes…
ALMA continuum observations of a 30 Myr old gaseous debris disk around HD 21997
A. Moór, A. Juhász, Á. Kóspál +10
Circumstellar disks around stars older than 10 Myr are expected to be gas-poor. There are, however, two examples of old (30-40 Myr) debris-like disks containing a detectable amount…
ALMA observations of the molecular gas in the debris disk of the 30 Myr old star HD 21997
Á. Kóspál, A. Moór, A. Juhász +9
The 30 Myr old A3-type star HD 21997 is one of the two known debris dust disks having a measurable amount of cold molecular gas. With the goal of understanding the physical state,…
A resolved debris disk around the candidate planet-hosting star HD95086
A. Moór, P. Ábrahám, Á. Kóspál +11
Recently, a new planet candidate was discovered on direct images around the young (10-17 Myr) A-type star HD95086. The strong infrared excess of the system indicates that, similarl…
Molecular gas in young debris disks
A. Moór, P. Ábrahám, A. Juhász +7
Gas-rich primordial disks and tenuous gas-poor debris disks are usually considered as two distinct evolutionary phases of the circumstellar matter. Interestingly, the debris disk a…
