Is 2021 PH27 an active asteroid with a meteor shower detectable on Venus?
Albino Carbognani, Paolo Tanga, Fabrizio Bernardi
The recently discovered near-Earth asteroid 2021 PH27 has the shortest orbital period of all known asteroids. It cannot be excluded that 2021 PH27 is also an active asteroid, as (3…
Use of the Semilinear Method to predict the Impact Corridor on Ground
L. Dimare, A. Del Vigna, D. Bracali Cioci +1
We propose an adaptation of the semilinear algorithm for the prediction of the impact corridor on ground of an Earth-impacting asteroid. The proposed algorithm provides an efficien…
Low delta-V near-Earth asteroids: A survey of suitable targets for space missions
S. Ieva, E. Dotto, D. Perna +7
In the last decades Near-Earth Objects (NEOs) have become very important targets to study, since they can give us clues to the formation, evolution and composition of the Solar Sys…
Yarkovsky-driven impact risk analysis for asteroid (99942) Apophis
D. Farnocchia, S. R. Chesley, P. W. Chodas +5
We assess the risk of an Earth impact for asteroid (99942) Apophis by means of a statistical analysis accounting for the uncertainty of both the orbital solution and the Yarkovsky…
Identification of known objects in solar system surveys
Andrea Milani, Zoran Knezevic, Davide Farnocchia +9
The discovery of new objects in modern wide-field asteroid and comet surveys can be enhanced by first identifying observations belonging to known solar system objects. The assignat…
Innovative observing strategy and orbit determination for Low Earth Orbit Space Debris
Andrea Milani, Davide Farnocchia, Linda Dimare +2
We present the results of a large scale simulation, reproducing the behavior of a data center for the build-up and maintenance of a complete catalog of space debris in the upper pa…
Planetary nebulae in the elliptical galaxy NGC 4649 (M 60): kinematics and distance redetermination
A. M. Teodorescu, R. H. Mendez, F. Bernardi +3
Using a slitless spectroscopy method with (a) the 8.2 m Subaru telescope and its FOCAS Cassegrain spectrograph, and (b) the ESO Very Large Telescope (VLT) unit 1 (Antu) and its FOR…
Planetary nebulae in the elliptical galaxy NGC 821: kinematics and distance determination
A. M. Teodorescu, R. H. Mendez, F. Bernardi +2
Using a slitless spectroscopy method with the 8.2 m Subaru telescope and its FOCAS Cassegrain spectrograph, we have increased the number of planetary nebula (PN) detections and PN…
Long-term impact risk for (101955) 1999 RQ36
Andrea Milani, Steven R. Chesley, Maria Eugenia Sansaturio +3
The potentially hazardous asteroid (101955) 1999 RQ36 has the possibility of collision with the Earth in the latter half of the 22nd century, well beyond the traditional 100-year t…
Updated analysis of the dynamical relation between asteroid 2003 EH1 and comets C/1490 Y1 and C/1385 U1
Marco Micheli, Fabrizio Bernardi, David J. Tholen
The asteroid 2003 EH1, proposed as the parent body of the Quadrantid meteor shower, is thought to be the remnant of a past cometary object, tentatively identified with the historic…
Discovery of the heavily obscured supernova 2002cv
A. Di Paola, V. Larionov, A. Arkharov +5
On the 13th of May 2002, supernova 2002cv was discovered using a near-infrared camera working at the AZT-24 1.1m telescope at Campo Imperatore (AQ-Italy). After the infrared detect…
