Objects without name in LMC

[jsmoraes (Jorge)]

Structures that I found in LMC without register or name.

Any one want to confirm them as object ?

Maybe some ones are only visual cluster, without gravitational interaction. What you think about ?
If you want, post a photo here also. Perhaps it will help to decide what they are.

Photos of them can be seen at http://jsmastronomy.30143.n7.nabble....Cloud-f97.html

Hello Jorge,

These objects don't get very interesting names.You can search for them using Simbad


Near NGC 1866

RA: 05h12m38.272s DE: -65 48' 59.16" = KMHK 657 (but there are others nearby)

RA: 05h14m50.066s DE:-65°18'49.70"= KMHK 676 or LW170 or SL63 333

The others would have similar catalogue numbers (maybe).

Regards,
Tony.

Great news, Tony !
I already knew Simbad, but I am not confortable in use it.
No chance, I will work with it to find the others.

I will try the links to see if I get some information about them. Normally I only find abstracts, but without permissions to download or access the full document.

My final image of this cluster attached. It seems that I got a bit similar resolution.

note: I did correction of the image. Now it is surely correct

[jsmoraes (Jorge)]

And the other: KMHK 676

[jsmoraes (Jorge)]

The two objects near NGC 1991 and NGC 1955

KMHK 640 - Cluster of stars

KMHK 885 - Cluster of stars

note: amazing how my resolution is very similar to the DSS !

[jsmoraes (Jorge)]

Near NGC 1818

KMHK 507 - Cluster of stars
BRHT 27b - Cluster of stars
KMHK 500 - Cluster of stars
BSDL 486 - Cluster of stars

This is a good catalogue for both the LMC and SMC
Catalogue of extended objects in Magellanic Clouds (Bica+, 2008)

Thank you, Glenc. I did a fast test with it, but I didn't get success in find objects by RA and DE. I need more time to experiment it.

With Aladin, using RA and DE from a star near the object, I find it and compare with my photo. If I am sure they are equal, I search in Simbad the region with de RA and DE from Aladim. And I search for the name of object.

It is not easy, because you can don't find a name or identification. This was the case of clouds below.

Near NGC 2003 and NGC 1978

Cluster (HD 269730) and Nebula
note: the clouds area haven't a global name.

ESO 86-2 and BRHT 37a - Cluster of stars

Well done Jorge,

It's interesting to see these minor objects get some attention. Your resolution seems maybe a little better than DSS.

Tony.

[jsmoraes (Jorge)]

It is more than only minor objects, Tony. As I always say LMC galaxy is a very interesting body near us.

Some people say it is a satellite galaxy. Others say that it is a traveler galaxy with enough speed to escape from the gravity of Milk Way.

Most people say that it was left with low activity and star formation up to contact with Milk Way. It is a body similar to those of the begining of the Universe that take ignition and wake up.

Therefore we are seeing in real time how a prior cloud is becoming in fact in a galaxy.
If it will join the Milk Way or continue its trajectory is still a question. But no doubt will no longer be the same until this situation is defined.

I think it is very important to register those DSOs to be material of camparisson in the future. And with ESO observatories in Chile we are doing it with more accuracy.

Much time was last without many registers because of the lack of observatories in south hemisphere. Only few Australians and Africans and all of small ability, if compared with the current ESOs.

My photos are not important, but the fact that I can capture these objects makes me feel that I am following in the footsteps of willian Herschel - name of my Observatory.

He discovered many, I confirm: yes, believe me, they are there, yet !

Nicolas Lacaille discovered the Tarantula nebula, NGC 2070 in 1751.
James Dunlop was the first to catalogue the LMC and SMC in 1826.
John Herschel catalogued the LMC and SMC between 1834 and 1838.
