Track: FROM DENSE CORES TO PROTOSTARS 1
What are the basic chemical mechanisms that led atoms to molecules in star forming regions? What is the role of the pre-solar chemistry in the present chemical composition of the Solar System bodies, planets, comets, and asteroids? The molecular complexity builds up at each step of the process leading to star formation, starting from simple molecules and ending up in Complex Organic Molecules (CO ... More

An increasing number of complex organic molecules have been found in the interstellar medium, in particular in regions where new stars are being formed. While a few of these molecules have recently even been traced back to the prestellar phase in low-mass-star forming regions, the bulk of their emission in the gas phase is detected during the early accretion phase, when the newly-born protostar st ...

Protostars and disks are formed within infalling envelopes of molecular gas and dust. The mass infall rate sets many of the conditions for early disk evolution. High infall rates may increase the mass of the protostellar disk enough to force gravitationally instability leading to the formation of binaries or planets and to episodic accretion from the disk to the protostar. Until recently, o ... More

Track: FROM DENSE CORES TO PROTOSTARS 1
The origin and history of prebiotic chemistry in protostars and protoplanetary disks is a main research theme within astrochemistry. With current observational facilities it is becoming possible to routinely detect complex organic molecular species, and also to study their spatial distribution and relative abundances throughout protostellar envelopes and embedded protoplanetary disks. We will show ... More

The two stable less abundant isotopes of hydrogen and nitrogen, D and 15N, are both enriched in comets and carbonaceous chondrites with respect to the values measured in the proto-solar nebula. This raises the question whether the two enrichments have a common origin, and how both are linked to the past chemical history of the Solar System. I will present new low-angular resolution observations of ... More

While there have been numerous studies of the disk and jet chemistry in evolved T Tauri stars, observations of the jet-disk system in protostars are very difficult due to their embedded nature and to the occurrence of numerous other kinematical components in the circumstellar region (cavities of swept-up material, infalling envelope, static ambient cloud). I will show how to exploit the combina ... More

The formation of disks and binary systems is thought to begin early in the star formation process. However, there have not been sufficient numbers of young protostars observed with high enough resolution to determine when and where most binaries and disks form. To significantly improve our knowledge of protostellar disks and multiplicity we have carried out the VANDAM survey, a 264 hour Jans ... More

Type: Review talk Session: FROM DENSE CORES TO PROTOSTARS (I)
Track: FROM DENSE CORES TO PROTOSTARS 1
Protostars in their earliest, deeply embedded, stages provide an important astrochemical laboratory, serving as the evolutionary link between dense regions in molecular clouds and the end-products in terms of the emerging protoplanetary disks. In recent years significant progress has been made on understanding the physical and chemical evolution of young stars during through stages. In particular, ... More

Track: FROM DENSE CORES TO PROTOSTARS 1
One of the major questions regarding the origin of life on Earth is whether the original mechanism that led from simple molecules to life was connected to metabolism or to genetics, both intimately linked in living beings. Formamide (NH$_2$CHO) contains the four most important elements for biological systems, and it has recently been proposed as a precursor of both metabolic and genetic material, ... More
