Discovery of an icy and nitrogen-rich extrasolar planetesimal
Snehalata Sahu, Boris T. Gänsicke, Jamie T. Williams +7
White dwarfs accreting planetary debris provide detailed insight into the bulk composition of rocky exo-planetesimals. However, only one Kuiper-Belt analogue has been identified in…
Constraints on Remnant Planetary Systems as a Function of Main-Sequence Mass with HST/COS
Lou Baya Ould Rouis, J. J. Hermes, Boris T. Gänsicke +8
As the descendants of stars with masses less than 8 M on the main sequence, white dwarfs provide a unique way to constrain planetary occurrence around intermediate-mass s…
white dwarfs within 40 pc III: spectroscopic observations of new candidates in the southern hemisphere
Mairi W. O'Brien, P. -E. Tremblay, N. P. Gentile Fusillo +31
We present a spectroscopic survey of 248 white dwarf candidates within 40 pc of the Sun; of these 244 are in the southern hemisphere. Observations were performed mostly with the Ve…
First detection of a disk free of volatile elements around a young A-type star: A sign of collisions between rocky planets?
M. E. van den Ancker, N. P. Gentile Fusillo, T. J. Haworth +7
Aims. We present the first detailed analysis of the astrophysical parameters of the poorly studied Sco-Cen member HD 152384 and its circumstellar environment. Methods. We analyze n…
An independent test of the photometric selection of white dwarf candidates using LAMOST DR3
N. P. Gentile Fusillo, A. Rebassa-Mansergas, B. T. Gänsicke +7
In Gentile Fusillo et al. (2015) we developed a selection method for white dwarf candidates which makes use of photometry, colours and proper motions to calculate a probability of…
